Amazon chose as Best Song of 2010 "F**k You," by Cee Lo Green. The track's a lot better than it might be—it's playful, beautifully performed and produced, and it grooves nicely—but its lyrics render it juvenile, in ways beyond vulgarity. That Amazon put it first says a lot about the culture. For contrast, check Amazon's list of 2010's best books. Whether or not you like them, they're books written for adults. In pop music, though, immaturity reigns. No wonder I buy so little of it.
(Here's my favorite song, by far, of the year. Of the past few years, actually. It didn't make Amazon's list.)
