Other than that... if I want music, I fire up Windows Media Player. Cop-out in a way, yes, but a good solution nonetheless
I do the same with the radio on my desk between my two computers. I start playing a painfully quiet space map like BoY and i turn on my StarWars soundtrack to the episode 4 opening or the cantina band. Then when I tell people what im listening to half the server replies "me too!"
