Did Chris Brown blow his chance at a redemption song at last year's Grammys?
Brown attracted a hail of criticism after he was allowed to perform twice during the awards ceremony, his first appearance since 2009 -- when he missed the show after his arrest on suspicion of felony assault on his then-girlfriend Rihanna.
Ken Erlich, executive producer of the Grammys, defended the move last year: "We're glad to have him back," Erlich said after the performance by Brown, who also won a Grammy that night for best R&B album for "F.A.M.E." "I think people deserve a second chance, you know."
But some performers and many in the Twitter universe disagreed, calling Brown a "wife beater" and other names. Many complained that Brown did not display remorse. And several missteps since then -- including Twitter rants and a foul-mouthed feud with a comedian, a violent meltdown backstage at "Good Morning America," a leaked nude photo and an apparent reconciliation with Rihanna -- have further tarnished Brown's reputation.
