"Blurred Lines" is easily the biggest song of the summer. Seriously. Turn on a radio station and you'll hear it almost instantly. And although I dislike the video (it's pretty sexist in my book: naked women being treated like props), I still love the song. All those "woo"s in the background and the cowbell make me so giddy.  The best "cover" of this song is from Jimmy Fallon, Robin Thicke and the Roots. The best part? They use classroom instruments. Check it out.
