Hi
Did you hear about Jango.com radio station? I accidentally jumped on their web site and found something interesting. If you have PayPal you can start playing your own songs and broadcasting on-line for just $10 and will have 300 plays.
If you have some other infos, would be nice to hear.
Anyway I tested it with my old song [done in 1997] - breakbeat created in OctaMED Sound Studio.
