Has anyone used this program or others like it? It allows you to raise or lower the pitch of any MP3 song and change the tempo without changing the pitch.

I need a program that will do this, but only this. I don't need other features.
I would like OSX compatible, but I can deal with XP if I have to.

reviews? recommendations?
