TeamXBox.com have posted a cool little tip on how to enable custom soundtracks on backwards compatible games on the XBox 360.
It's a bit of a hack, and one problem is that the music will play along with additional background music, so the best idea is to use a game that allows you to turn off the soundtrack.
If you're Brian Crecente, all you have to do is simply go into the music player, put on the Weather Sister's It's Raining Men!, then boot up a backwards compatible game like Halo 2 and flounce about to a startlingly appropriate background music, considering your general deathmatch ability.
