Currently it is only possible to play/pause and switch songs. Please, add volume control, shuffle option and some information about the song playing (song name, duration, artist...)!!!
I know that it is hard to do an appropriate interface for a watch without touchscreen, but I have some ideas:
1) remove instructions from the screen - show them only on the first launch.
2) instead of instructions add some information about the song playing like in a mini music player
3) a music widget or application can be made
Buttons:
-Existing
1) arrow up - previous song
2) arrow down - next song
3) start - play/pause
-New
4) arrow up, holding the start button - reduce volume (as arrow up is also previous song)
5) arrow down, holding the start button - increase volume
6) hold arrow down - shuffle songs
