I do promotions for the station, which is partially why I joined this community..
RTDS has over 50,000 tracks, and all genres of metal, as well as listeners being able too request every 14 minutes. If you donate to the station however, your req time will be cut in half. There's also an IRC server as well, which can be found on the web site. So, everyone must check out the station/IRC server, and spread the word. \m/
