Migrating radio station to Linux

allikat_uk writes: I'm a DJ for a net radio station (amongst other hobbies). I want to migrate from an XP platform running (SAM Broadcaster) to a Linux based solution. I don't need to host the server, as the station does that, I just need a nice graphical interfaced solution to stream the MP3 files to the server. I need to run 2 streams, 64k stereo, and 22k mono in MP3 to a shoutcast clone server. My current software has a nice MySQL database to make finding the tracks I want quickly, dual playback "decks" and easy voiceovers. Is there a Linux equivalent available under GPL?
Helpful replies appreciated.
