The app is great already, but it would be perfect if you could choose the player (like in the browser interface), as I only use Subsonic to stream the music to my internet radio receiver. With the app the music starts playing on my computer, I found no way to stream it to the internet radio receiver.
Without the streaming the app is useless for me, unfortunately.
EDIT:
Using Opera Mobile browser it is possible to choose the player (in Android Stack browser the drop down menu is not working), so I can improvise to solve my problem.
One more great thing would be if Internet Radio/TV streams would be actually streamed through Subsonic, so that I could switch to them without having to change the channel on my Internet Radio device, as I want to remote control the whole thing with my Android App from a different room.
