That's all very possible. Demi is more like rock with a pop edge. And for the record, I know more of Taylor Swift than Taylor Momsen, so I can't talk about Taylor Momsen except that she looks... a little all out there. Anyhow, Demi Lovato could very well fill the void when moving on from Disney and "Sonny With a Chance." I like Demi MUCH more than Avril Lavigne, whom I've never liked and never had a favorite song of hers. You know... where in music will she be when she becomes 21? We'll have to see where her music interests lie when that time comes.
