Okay, I'll admit SOME of her live performances are a little offkey... but she can be amazing live most of the time. She was so-so at the Grammy's,but she was amazing at the Rock&Roll Hall Of Fame. I don't think her songs are too similar all the time... she only has 11-12 songs for god's sake. Just listen to "Wanted" and "Twilight" those 2 songs definitely took it for me. Her new song is featured in the new PS2 game Spy Hunter 2... Her new album, set to release in spring is going to have a gothy sound to it, she claims to have only 1 love song on the whole album, so i'm looking forward to some of her darker work.
*her lyrics i don't think are based on rhyme at all
you seem to just be basing your opinion of her on that one song "A Thousand Miles". It was her debut single, I don't think she planned to make it that meaningful, you know american mainstream music today, built on catchiness... She just wanted to make a name for herself.
