how do you mean dependant on the framerate? does the music stop if your 
game gets too slow? or does the tempo go faster if the framerate goes up?

on windows platforms, SDL_mixer uses the windows native midi playback 
for midi music. on other platforms it uses timidity. you can build 
SDL_mixer for windows that uses timidity instead.

the bug must be somewhere in SDL_mixer's handling of the native midi 
playback. i don't know if it's the sort of thing that pygame is going to 
be able to work around.

can you determine what part of the faster framerate is making the music 
change? i am guessing it is some pygame.event queue function, since SDL 
does a bit of polling and updating when updating the event queue. 
although i'm surprised anything inside SDL_mixer is getting effected by 
this?
