I'm assuming it's running on SHOUTcast, yes?
I was thinking that it could be improved with DJs or some sort of radio show. Like, maybe even just a weekly show with different DJs playing their own music, or show like that with a bunch of DJs just discussing stuff or taking requests from the chat room. If you've ever listened to Suprnova Radio, something like Schizo Hour would be cool (except toned down a bit, so it's more PG or PG-13).
Yeah. Just suggestions. I have a chem test to study for. I am outie-5000.
