Well they actually review the soundtrack but below is the part about Rob.
Thanks to AJ for this find :-)
Rob Pattinson, who plays Edward in the film, is a musician himself, and contributes the simple and effective “Never Think,” an inclusion that refreshingly doesn't come off as a crass marketing gimmick (“OMG, teen vamp hottie sings!”) thanks to his superb vocal skills. Actually, word has it director Catherine Hardwicke quickly opted for the song after hearing a CD of Pattinson's earlier material. If he ends up riding the film's in-the-bag success to a decent recording contract, I'd wager he's off to a pretty good start here, and could be a name to watch in the future.
