It's tough to keep track of your music. To help, Spotify offers a library to which you can save your favorite tracks. If you've been using Spotify for a while, though, you'll know that your saved songs can add up. Through quantitative and qualitative user research, it became clear that navigating the library is a pain point within Spotify's mobile app.
Consequently, avid users tend to avoid the library feature entirely, using organized playlists as a workaround. Below is an example from one such user's account.
In this concept, the user's saved songs are pre-organized into playlists based on the date and location at which they were saved. Want to listen to the songs you saved during your senior year of college? No problem. What about the music you discovered years ago on a trip to the Dominican Republic? It's right there for you.
In designing this feature, it was difficult to decide on the most intuitive design that would fit most elegantly within the Spotify app. In order to inform my decisions, I extensively research mobile design best practices, studied the design language of the Spotify app, and explored analogous solutions within other apps and platforms. I then took this information, used it to prototype, and tested the results with users to see what is most effective.
Below is a screenshot of Spotify's native playlist information tray and a photo of the wireframe sketch closest to the finished project. I ultimately created a similar information tray within the saved songs library, expanding upon the current interface to allow for date and location-based filtering. The end results were a product of persistent iteration based on critical feedback from users.
The longer people listen to music on Spotify, the more important it will be to have a dynamic and easily sortable library. This feature will help keep the music you love today fresh and findable for years to come.
