Pebbe is a handy smart watch. So wouldn't it be nice to control Spotify right from your wrist?
The official music app just gives you the ability to skip tracks back and forward and play/pause. But the possibilitys are nearly infinite. Rate Tracks while listening to Spotify Radio or change the playback mode (shuffle/repeat). Star a track, adjust volume, skip and search in tracks. All right from your watch.
My idea: Multiple UIs, accessible via a long press of the middle button. There you can choose the screen: Playback screen: - up and down will skip tracks while holding them will search in track. - middle is play/pause On Volume screen up and down will adjust volume instead of back/forward.
Rating screen: - Up and down will rate the track while listening to Radio, if listening to playlist they will toggle shuffle/loop - middle will (un)star the current track.
Playlist selector - Browse through your playlists and tracks - middle button to open playlist/play selected track, hold to get options: play next, play radio based on selection, hide (which will hide the selector and go back to last used screen); back navigation with back button.
Would be great and increase the users experience with Spotify. Radio will get even greater because if you (don't) like a track you don't need to take your phone out of your pocket or switch to the app.
