Droidcast

https://github.com/snogaraleal/droidcast
Droidcast is an Android library implementing a service for OGG Vorbis streaming. Although the Android media player does support OGG Vorbis, it doesn't provide live metadata from Vorbis comments. Droidcast uses the pure Java OGG Vorbis decoder JOrbis to play OGG streams, allowing you to listen to meta-data changes.
