Ne-Yo's latest is a concept album about crime-fighting "R&B superheroes," complete with a femme fatale and a thing called the Libra Scale — a device that measures the weights of money, power, fame and love. If you find that hard to follow, no matter: Just listen to the music. Ne-Yo has crafted an epic full of party songs, beatific ballads and throbbing spy-movie club music. It's lavish disco; the songs are cinematic in scope but have the unshakable hooks of great pop. If that formula sounds like a certain recently deceased R&B superhero — well, that's no coincidence. The real "concept" here is: Michael Jackson tribute album. And a damn good one.

“IRM”

Fashioned to mimic the sound of a magnetic resonance imaging or MRI, "IRM" (the French designation for the brain scan) grew out of Gainsbourg’s love of the sound of the clickety-clack of medical machinery. The IRM album project also marked the fulfillment of two goals for the singer: to document a traumatic experience, and to record an album with Beck. Though her co-creator and producer didn’t necessarily know the details of her water-skiing accident and resulting cerebral hemorrhage (which lead to the IRM of the song's title), he somehow knew how to handle the material. "Beck had a way of guessing what I was thinking and feeling without me telling him," said Gainsbourg. "We never discussed these things explicitly."
