Perhaps she puts on a good live show, but I certainly would not put on her album to listen to.
I was not a huge fan until I saw the Monster Ball Tour on HBO
she sings (no lip sync) she dances, she's great with the crowd, costumes, props, big sets...
and she writes her own music, which is probably the main reason I respect her more now
p.s.
I never understood the attraction to Coldplay, Modest Mouse, Taxicab for Cutie...
and those kinds of bands.
Also never got the attraction to metal bands like Metallica
who have a "formula" for a song and never stray very far from the plan
(then they say, it's not about the money, it's about the music)
I see the attraction to rap (for some people)
just never agreed with it
