I personally don't think Tremulous needs ingame music. That way you can hear a alien coming at you. I also think the menu-music must be removed. I know, you can put music sound all the way down(don't know why, because there is no music accept the music in the menu) but sometimes it just plays, even if you said Tremulous to quit the music.
Idea: maybe implement a Tremradio-Player in Tremulous 1.2, so you can play Tremradio in Tremulous

. (maybe it is just my computer but if I try to play Tremradio in Winamp and then open Tremulous, all the sound goes to the right box, really annoying

, I can fix this by moving the soundballance bar a bit and then move it back to the middle, then alt-enter back to fullscreen Tremulous. Somboddy know how to fix this?)
