Spotify Loop
Adding Micro Looping to Music Listening
A feature addition case study for Spotify that enhances how users interact with their favorite parts of songs.
🎯 Project Summary
TL;DR
Spotify doesn’t let users loop a specific song segment. Spotify Loop adds a minimal, native interaction to set start/end points and replay that moment. It improves practice, study, and enjoyment without cluttering the player. Next: validate discoverability, speed to loop, and satisfaction.
Constraints
- Must preserve Spotify’s minimal player UI; no clutter.
- Mobile‑first gesture design; accessible touch targets.
- API feasibility and performance assumptions noted for concept.
Collaboration & Feedback
- Feedback from music learners/guitar communities on precision vs. speed.
- Peer critique led to surfacing controls in a swipe‑up drawer.
- Planned usability tasks informed success metrics (time‑to‑loop, task success).
Problem
Spotify lacks a native way to loop specific song segments. Users who want to repeat a chorus, vocal phrase, or musical riff must rely on external tools, scrub the progress bar imprecisely, or leave the app—fragmenting the listening experience.
Success Metrics
- Reduce time-to-first-loop discovery to under 5 seconds
- Enable loop creation in under 3 drags on average
- 80%+ task success for set/adjust/remove loop in testing
- Satisfaction ≥ 4/5 for clarity and control
Before (Current)
Users scrub back and forth or use third‑party tools. It’s imprecise, breaks flow, and often takes them out of Spotify.
After (With Loop)
Drag to set start/end points, instant replay, saveable loops—keeps users in Spotify with minimal cognitive load.
Spotify Loop
An exploratory UX case study focused on enhancing user interaction within Spotify by allowing users to loop specific song segments. Targeted toward users who obsess over hooks, breakdowns, or instrumental sections, this feature adds a layer of personalization to passive listening. With music becoming increasingly social, emotional, and interactive, this feature bridges the gap between static playback and dynamic user expression.
My Role
This was a self-initiated case study to improve a widely used consumer product. Roles: Product Designer (UX/UI), UX Researcher, and Interaction Designer.
The goal was to apply product thinking, research, and design skills to augment an existing product with a minimal yet emotionally impactful feature.
🔍 Design Process
1. Empathize & Research
Research & Validation
To understand user needs and validate the opportunity, I conducted comprehensive research across multiple channels:
Reddit & User Communities
- r/guitar: "It's a pain moving the slider in Spotify over and over again… always starting at a slightly different spot."
- r/LearnGuitar / r/Music: Developers created tools like PractAid to loop Spotify segments because "there's no feature" natively. "PractAid lets Spotify Premium users loop segments of songs for music practice."
- r/spotify: Casual fans admit to looping full tracks mentally: "If I find a song I really like I'll literally listen to it on loop the entire day."
External Research
- A YouGov study (2022) showed 68% of musicians aged 16–34 use streaming platforms to practice, and 41% said they needed extra tools for segment replay.
- Moises.ai and AudioStretch have grown to millions of users, signifying widespread demand.
- YouTube Looper plugins see over 500K weekly users—a clear sign of consistent, cross-platform demand for segment looping.
Competitive Analysis
To understand how others solve segment looping, I reviewed popular tools in the music learning and listening space. The goal was to identify common interaction patterns, friction points, and opportunities to create a simpler, more native experience for Spotify users.
| Product / Platform | Loop Creation Method | Strengths | Weaknesses / Gaps |
|---|---|---|---|
| Moises.ai | Drag start/end markers on waveform | Visual clarity, precise selection | Requires leaving Spotify; heavier UI; learning curve for casual users |
| AudioStretch | Drag handles along a waveform timeline | Fine control over playback speed and loop points | App-switching disrupts flow; not integrated with streaming |
| YouTube Looper Plugins | Enter timestamps or click "Loop" button on video | Simple; works in browser | Lacks tactile mobile gesture control; not native to music streaming |
| PractAid (Spotify API) | Drag to set A/B points in separate app | Designed for practice use | Relies on Spotify Premium; UX feels external and segmented |
| GarageBand / DAWs | Drag region selection in editing timeline | Extremely precise | Overkill for casual listening; high cognitive load |

Key Insights from Competitive Review
- Integration Gap – None of the reviewed tools work natively inside Spotify's mobile player, forcing app-switching or desktop-only workflows.
- Discovery Problem – Most loop functions are hidden behind menus or require technical knowledge (e.g., typing timestamps).
- Precision vs. Speed Tradeoff – Waveform dragging is powerful for musicians but slower and more complex for everyday listeners.
- Emotional Engagement – Existing tools focus on practice/utility; few consider looping as a form of casual music enjoyment or social expression.
Design Opportunity
Spotify Loop can combine the speed of drag-to-set markers with native integration, removing friction and keeping the core Spotify experience intact—while still serving both learners and casual listeners.
User Journey Map Comparison
To visualize the user experience with segment looping before and after Spotify Loop, I created a journey map to identify emotional pain points and moments of opportunity in the current workflow.
The journey map reveals how users currently struggle with app-switching, imprecise scrubbing, and fragmented experiences when trying to loop song segments. Spotify Loop addresses these pain points by providing a native, intuitive solution that keeps users engaged within the platform.
2. Define
Problem Statement
How might we allow users to seamlessly loop a segment of a song within Spotify, enhancing their listening experience without disrupting the platform's clean UI or passive user flows?
Design Philosophy
Spotify is beloved for its minimal, smooth experience. We didn't want to change that. Instead of a redesign, this feature is an addition — something optional, discoverable, and complementary to existing controls.
We framed this around two beliefs: respect the music so listeners never lose access to full tracks or feel forced into looping mode, and empower deeper interaction so listeners can linger on the moments that move them — the beat drop, the lyric, the solo.
Constraints & Design Requirements
The loop feature must not interfere with the default play/pause/seek experience, should be intuitive for new users and accessible on mobile, and must not add visual clutter to the now-playing screen.
User Stories
The feature serves three key user types: listeners who want to loop specific parts without leaving Spotify, music learners who need to hear sections repeatedly for study, and casual users who don't want the feature to interfere with their normal listening experience.
Design Opportunity
Repetitive listening is part of music enjoyment, yet the interface for looping is awkward or absent. Spotify can embrace this behavior and enhance user delight with a micro-interaction that feels magical, not mechanical.
3. Ideate
I brainstormed multiple UI approaches, including waveform-based loop selection (visually appealing but technically demanding), tap-to-set markers (simple, scalable, and familiar), and press-and-drag timeline interaction (an intuitive touch gesture).
Final Concept: Tap-to-Loop Interaction
The final concept is a tap-to-loop interaction: tap once to set the start, tap again to set the end, and a loop icon appears when active. Tapping the icon disables the loop. On mobile, loop controls live in a swipe-up drawer under the progress bar to keep the main player clean while making the feature easy to reach.
User Flow Mapping
To ensure the interaction felt intuitive, I mapped out the complete user journey from discovering the loop feature to successfully creating and managing loops. This flow chart helped identify potential friction points and validate the tap-to-set interaction pattern.

4. Prototype & Design
Design Goals
The design aims to seamlessly integrate loop UI with minimal cognitive load, show clear visual feedback when a loop is active, and ensure touch-friendliness for mobile users.
Loop Feature Breakdown
The loop feature works through a simple tap-to-set interaction: users tap once to set a start point, then tap again to set an end point, with a light band appearing on the timeline. While the loop is active, only that segment plays on repeat, and users can exit with one tap. At any point, users can toggle off loop mode to resume full playback, ensuring the original song experience is preserved. Loops can also be saved to a dedicated "Looped Segments" tab under the track, accessible like bookmarks.
Where We Placed It (and Why)
On mobile, loop controls live inside a swipe-up drawer under the progress bar. This keeps the default UI clean while making the feature easily accessible — similar to lyrics or the queue.
Lo-Fi Prototype
With the concept validated through research, I moved into rapid prototyping to test the interaction flow. The low-fi wireframes focused on three key aspects: the loop creation process, visual feedback during loop playback, and the placement of controls within Spotify's existing interface.
Key Insights from Lo-Fi Testing:
Users preferred tap-to-set over drag interactions for precision, a subtle highlight band communicated the looped segment most clearly without conflicting with album art, and a swipe-up drawer kept loop controls discoverable while preserving the main player’s simplicity.
Refinements Made:
I simplified loop creation to two taps, added a brief confirmation to prevent accidental loops, and integrated loop controls alongside the existing playback buttons for familiarity.
Moving to High-Fidelity Design
With the interaction flow validated through low-fi testing, I began translating the wireframes into polished, pixel-perfect designs that would feel native to Spotify's design system. The focus shifted from functionality to visual refinement, micro-interactions, and ensuring the feature felt like a natural extension of the existing interface.
Hi-Fi Prototype
Spotify Loop is a feature that allows users to create and play custom loops of their favorite song segments. Users can set start and end points on any track, then play just that section on repeat. This feature is perfect for learning lyrics, practicing instruments, or simply enjoying your favorite parts of a song.
How Spotify Loop Works
1. Now Playing
The standard Spotify interface with the new loop button positioned below the main playback controls, seamlessly integrated into the existing player layout.
2. Set Loop Points
Users drag to set start and end points, creating a highlighted segment on the progress bar that will loop.
3. Loop Active
The selected segment plays on repeat, with clear visual indicators showing the loop is active and the current position.
4. Loop Saved
When loop mode is active, it counts as a new song and saves separately from previously saved versions, creating a unique entry in your library.
5. Saved Loops
Access all your saved loops in a dedicated library, with search functionality and the ability to organize your favorite song segments.
Design System Integration:
We used Spotify’s signature green (#1DB954) for loop indicators and controls to maintain brand consistency and accessibility, applied the platform’s font hierarchy and spacing for rhythm and readability, and designed icons that match existing stroke weights and visual style.
Micro-Interactions & Polish:
The experience includes smooth animations for loop creation and playback transitions, subtle haptic feedback aligned with Spotify’s interaction patterns, and loading/error states that feel native to the platform.
How It Works

Microcopy highlights include: “Set loop start”, “Set loop end”, “Loop this section?”, and “Loop on / Loop off”.
5. Test & Iterate
With the Figma prototype complete, I'm ready to validate the loop interaction design through comprehensive user testing and technical feasibility assessment.
Success Metrics
- Task completion rate > 90% for loop creation
- Time to set first loop < 15 seconds
- User satisfaction score > 4/5
- Zero critical usability issues
Technical Considerations
- Integration with existing Spotify player API
- Loop state persistence across track changes
- Performance impact on playback engine
- Cross-platform consistency (iOS/Android)
Implementation Strategy
The feature would be implemented as a phased rollout: first to Premium users as a beta feature, then gradually expanded based on usage data and feedback. This approach allows for iterative improvement and risk mitigation.
Business Impact
Implementing a native segment‐looping feature could significantly boost Spotify's key metrics. Highly engaged listeners – such as musicians and active learners – would spend more time in-app repeating favorite parts of songs. This deeper engagement has been linked to better business outcomes: Spotify research shows that users with more diverse listening habits are ~25% more likely to convert from Free to Premium (research.atspotify.com), and similarly have 10–20% lower churn (research.atspotify.com). By keeping practice-minded users engaged in Spotify (instead of using external tools), the loop feature helps drive these positive trends. In practice, real users already seek this functionality; for example, one musician built a third-party app to loop Spotify segments "to alleviate my own pain point" (reddit.com), illustrating clear demand.
Higher user engagement and retention: Allowing loops lets users linger on beloved song moments, increasing session time. More engaged listening correlates with higher retention and satisfaction (research.atspotify.com) (research.atspotify.com). This means users are likely to stay in the app longer and return more often, reducing drop-off. As one Reddit user noted, musicians "literally listen to [a song] on loop the entire day" when they love a part, indicating that built-in looping would capitalize on this behavior.
Increased Premium conversion: Adding a sought-after feature enhances Premium's value proposition. Many practice-oriented users already need Spotify Premium to use external loop tools (e.g. PractAid requires Premium (reddit.com)). By natively providing looping (initially to Premium users), Spotify could encourage free users in this niche to upgrade. With 626M monthly users and 246M paid subscribers (≈39% conversion) (newsroom.spotify.com), even a small bump in conversion rate among engaged users would translate to millions in additional subscription revenue.
Market demand validation: The huge adoption of third-party loop and practice apps shows broad user interest. For example, Moises.ai (an AI practice app with looping) boasts over 60 million users worldwide (prnewswire.com), and Looper for YouTube has ~400K users (chrome.google.com). These figures illustrate that many people rely on looping tools for learning and enjoyment. A native Spotify loop taps directly into this proven market, reducing friction and potentially drawing users from these external solutions back into Spotify.
🧠 Reflections & Takeaways
Spotify Loop might seem like a small tweak, but it aligns with evolving user behavior. From TikTok loops to study playlists, people want music to be modular, not just linear. This feature empowers listeners to connect more deeply with songs by focusing on moments.
"I love the drop at 1:42 — I wish I could just stay there."
As a designer, this project taught me the value of zooming in: finding overlooked behaviors and building features that feel obvious once they exist.
📈 Future Enhancements
Planned enhancements include saving loops as mini-bookmarks tied to tracks, sharing loops with visual/audio snippets, creating playlists of favorite segments, and adding loop insights to Wrapped (e.g., “Your most-looped moments”).
📍 Final Thoughts
This case study pushed me to think deeply about micro-interactions and user emotion. Spotify is about more than streaming — it's about how music fits into life. Looping gives users more expressive power in how they listen, learn, and love their favorite tracks.
