Sources for German Music
If you want to hear some great German music on the radio, check out Radio Goethe. It's a one hour radio show based out of San Francisco, USA streamed online every Thursday night/Friday morning devoted to purely German music!
Another radio station to check out is R1Live. The station is on all day, every day and plays goth, synth, techno, etc. Most of the music is from German artists with the occasional international artist thrown in.
