Spotify

Spotify's interface is built on the horizontal shelf: row after row of round and square covers you swipe through, stacked into an endlessly scrolling home. The signature move is how it personalizes the containers themselves, not just the contents. Daily Mixes, the Made For You hub, and the year-defining Wrapped all turn listening history into named, browsable objects. Playback lives in a persistent bottom bar that survives every screen, so you never lose the thread of what's playing. The weak spot is discovery friction at the edges: queue management is buried, the line between your library and Spotify's catalog blurs, and the home feed increasingly mixes podcasts and ads into music shelves, making it harder to act on a clear intent.
