M4A/OGG/AAC Player: Microfi Nitrogen 1.1
 

Just came across this media player. It's got a nice UI built in but it's also open source so feel free to edit at will! The best part, IMHO, is the fact that it can play MP3/OGG/AAC/MP4/M4A/3GP/WAV/WMA. Yeah, just about everything.

Enjoy

I love Nitrogen. Now if only they would support AVRCP then I would use it all of the time.
