If there's a collaboration we didn't know we needed in our lives until right now, it's Ozzy Osbourne fronting Earth, Wind & Fire. Unfortunately we'll probably never see that in our lifetimes, so we'll just have to settle for this mashup of "Crazy Train" and "September," which I'm willing to bet you're going to listen to quite a number of times today.
Seriously, this is so undeniably funky.
