To be honest I would say Mark Ronson is the reason why Whinehouse doesn't suck more. No disrespecting your taste in music but she can't sing where as this guy is a talented musician. Valerie was a crappy cover not because the music sucked, I like the Zutons version more but Ronson didn't ruin it, her vocals did.
I just heard Get out and Get it and a couple of others. Hmm, they aren't hurting anyone but there are enough better bands on this site alone for me to concern myself with.
