Music Video Tuesday! Ok, that’s not a real thing, but that’s our theme of today’s round-up of Youtube video covers. Admittedly, the last video isn’t exactly a music video so much as it is a gigantic mash-up of footage. But when you’re dealing with 50 different artists and trying to work all those clips together, we figure it’s just as much work as any other MV production, so we’ve gone ahead and included it too. Enjoy!
