So, unless you've been living under a rock, you've no doubt heard the dulcet, melodious tones of Friday, by Rebecca Black... You've probably also come across the bazillion or so parodies of it. Well, I was watching MTV Hits tonight and heard the new song, Last Friday Night (T.G.I.F.), by Katy Perry. I can't guarentee it was originally meant to be a response to Rebecca Black (I don't know which one was written first) but it definitely is now - Rebecca Black is even in it (so, all those people who made fun of her, well, who's laughing now?). Of course Katy Perry's is way better and the official video is actually a mini movie complete with well-known actors and musicians in key roles. I'm posting both here so you can compare them, but if you haven't listened to Rebecca Black yet, bear in mind, I've never actually been able to make it all the way through the Rebecca Black song, so be warned.

Without further ado...
