Increase the max volume output in songbird?

Is there a way to? I know in VLC you can set it, and Winamp seems to output quite a bit higher than songbird. I know I could obviously just crank up the volume on the speakers themselves, but as it stands, if I decide to go and play games (or do anything involving audio) while listening to music, I don't get the right balance. (and it'd be a pain in the rear to go in and adjust all of my programs around SB)

IE.

GTA + Songbird = Volume in Songbird too low even at max
GTA + WINAMP = Perfect at 50%

It would just be nice if those could be adjusted to increase (or decrease) the max Output so we can if we need/want to. This of course all being if we don't already have this ability to do this.
