I'm trying a little bit more your OS and like it a lot !
Work great !
Just some Suggestion :
- As already said BerryBoot compatibility
- Simple GUI interface, just for the title, artist, album, even if it's not controllable. I plugged it on my TV and have pi@Raspyfi:~$ not really cool (may be i miss something ?)
- Support for : Spotify, Deezer and Grooveshark ?
- A button to empty Playlist in one clic

I'll comeback if some ideas come later
Thx.
