The "Glee" kids' clean, Autotuned voices washed all the passion and quirk from Florence and the Machine's "Dog Days Are Over." Even stripped down and live, Florence and the Machine does it better:
Amy Winehouse's "Valerie." Yes, I know this is a Zutons song, but I prefer Winehouse's slower, soulful version. I wanted to embed the singer doing this song live, cause it's amazing. But embedding is disabled on that video. Enjoy the one below, but check this out, too.
