Does anyone of you know
Rainwave? I just discovered it and it is quite neat. It is basicly a Video Game Radio with 5 different stations:
All: just a mix out of all other stations
Game: Video Game Soundtracks
Chiptune: Only Chiptune
OC Remix: All OC Remix tracks
Covers: Official and fan made tracks
When a song is playing the site gives 3 options for the next song. When you have an account there you can vote for one of the 3 tacks. If you do not have an account just listen to the one that is getting picked.
It feels a bit like a jukebox. You never really know what you get and you can let it stay in the background. You can also use .mp3.m3u or .ogg.m3u to hear it inside your media player (I use Foobar2k but you can basicly use anything).
