She's doing better work than a lot of other pop stars out there, especially the manufactured ones coming from the Idol factory, who seem to own the world at the moment. I don't think her talents would be better served giving conservatory recitals in ill-fiting silk charmeuse get-ups.
She has a great singing voice, she writes/composes, she actually plays an instrument. I saw her on SNL and she broke down one of her hits to just her at a piano, and she started improvising lyrics tailored to being on the show and in New York...her momma may dress her funny, but she's the real deal. She's crazy, but on the side of the angels.
