I thought we had one of these, but I guess not.
I was thinking as I was trying to add music to certain stages that for some its pretty hard to think of a fitting song sometimes, and a fight without music gets pretty boring.
Basically just post what stage you have that doesn't have music, then the community can suggest a good fit, and stages of theirs that could use music.
(I can't think of any that I need music for now, besides a few Simpsons stages and the Flintstones one, since the theme songs are too short)
