I recently found the plugin for Rhythmbox (the standard music player shipped with Ubuntu) which lets you control the playback from any other device in the network via a web interface. Unfortunately this web interface is very limited: It only allows to play/pause and move to the previous or next track.
Is there another music player that has a web interface that lets you control more things?
For example I'd really like to have the overview that lets you choose an artist or an album directly, without having to click through hundreds of tracks.
