No, she wasn't that good. She was good, to be sure, but believe me when I tell you it isn't that hard to write a song where 75% of the words are simply repeating "the edge" over and over and over again, or turning "hanging on a moment of truth" (whatever that means) into "hanging on a moment with you" (whatever that means).
She can sing, sure. I appreciate that she writes her own music and lyrics which is something almost all the other pop tarts can't say. Still, the songs aren't particularly creative. The music is pretty standard pop arrangements and the lyrics are sadly very trite.
I guess I'm not as easily amazed.
