re: Hanson phenomena
Or at least subconscious jealousy. Ever go onto gossip websites and notice how the posters have nothing but nasty comments for the female celebrities, but have nothing but praise for the male ones? Most of the posters are women/girls.
As for "rocking harder than Avril", I don't think so. She covers Avril's "Daydream" and changed the lyrics to be more "appropriate". I figure that if you're catering to a 10-year-old audience, it's pretty hard to rock out. Same goes for the Jonas Brothers themselves.
That being said, I hope her album is more like her first single than the awful awful awful awful "This Is Me".
