I thought his performance of the new (?) song "Pretty Amazing Grace" on American Idol was a total flop. Not the actual performance, but the song itself. Easily one of the worst new songs I've heard in a while. Then again, I wouldn't call myself a fan, either.
Even a wonderful supremely talented artists can have an off day. For me, Tori Amos has no equal and yet I HATED her album Strange Little Girls. I thought she'd give each song her typical unplugged piano treatment, but the songs were all s**te.
It really pains me to say it but I never listen to it anymore. I should have known, though. The critics loved it, so it stands to reason I wouldn't.
