Backstage Pass

Experiments and artsy second-guessing seemingly behind her, Jennifer Lopez is back to doing what she does best on her new single "Do It Well" (Epic). Written and produced by Timbaland protege Ryan "Alias" Tedder, the lead single from Lopez's forthcoming album "Brave" is upbeat, streetwise and sultry, with some disco-era strings and a big beat that give her ample opportunity to combine the dance-floor vibes of "Love Don't Cost a Thing" and "Waiting for Tonight." They will also help her fiercely strut her way to another mega-hit.
