I, unfortunately, saw Valentine's Day, which features Taylor Swift as a hyper-happy high school student, and SHE WAS TERRIBLE. She was in the movie for maybe five minutes. She was so unnatural. So stiff. Now she's going to be Joni Mitchell?
But if not Swift, who? I suppose, as far as young, female singer-songwriters go (who, you know, actually sing and write their own music), Swift is the obvious choice. Do you have any better ideas?
