2012 Winners and Losers in music so far: Madonna, Adele, Lana Del Rey
How are Chris Brown, Jack White, Black Sabbath, Carly Rae Jepsen and Bieber faring?
Loser: Jennifer Lopez
Despite the hype and over-hype generated by her "American Idol" spot last year and No. 3 single "On the Floor," J-Lo wasn't able to gain any new traction this year with new single "Dance Again." Plus, if you paid attention to sales and ratings, "AI" isn't doing so hot either.
