Let's discount Costello for an obscure cut from a soundtrack to a movie (De-Lovely) that nobody saw. Ditto for Groban, who, with his operatic baritone and classical crossover song, doesn't seem like the right fit here. Mayer rightfully won in this category two years ago for "Your Body Is a Wonderland," but he works his sensitive singer-songwriter shtick a little too much on the sappy "Daughters." It would be nice to see Prince win, if only to make up for the fact that, despite his big comeback in 2004, he did not get an Album of the Year nomination for Musicology. The class of the field, though, is Seal, who also took this prize home for "Kiss from a Rose" in 1996. He brings a soulful, spiritual urgency to his sumptuous ballad from Seal IV that is truly something divine.
