It's not for me but I think the app looks good and the animations are gorgeous. Listen lacks traditional playback controls or buttons, relying on gestures, swipes, and taps to play, pause, and skip music. The idea is that you can drag the album artwork around to trigger various actions, but it works well for some things and not so much for others. I think developers have to keep in mind that removing buttons adds a lot of complexity — in this case something simple like playing a song over AirPlay requires a very specific drag gesture. Listen's great for shuffle play, but not so much for rummaging through your music collection. Also, what's up with circular artwork lately?
