A small update:
I am currently developing a new music player which will replace the rather limited Onyx player. It uses the
MPD music server.
The implementation is now in a usable state, so I uploaded a video on YouTube to demonstrate it:

At this moment mp3 and flac files are supported but I want to add ogg and wav support as well.
Further you can browse your music by Title, Artist, Album, Genre etc.
There is one issue at the moment; when flac files are played without a power connection the device enters some power-save mode and playback stops
If you have suggestions to improve things, please let me know.
