"Discipline" by Janet Jackson; Island Def Jam

You'd think that after the flops of her last two sexually charged albums — "Damita Jo" and "20 Y.O." — Janet Jackson would be in full career-reinvention mode. Instead, on her latest disc, "Discipline," Jackson plows ahead down a similar path, teasing and titillating over dance-club beats and sultry-sounding ballads. The results, however, are decidedly mixed.

Despite a lukewarm reception on radio, the disc's first single "Feedback," is classic "sexy, sexy, sexy, sexy" Janet. The track's electro-synth melody and pumping bass line make for automatic dance-floor fodder.

Other highlights on the disc include "Luv," built on similar whiny synths and processed keyboards that T-Pain has popularized, the foot-stomping "Roll-ercoaster" and the pop-house track, "Rock With U." But too many between-song skits and slow jams detract from the disc's good times.

By disc's end, her message becomes painfully obvious: Jackson's a hot fortysomething with a sensitive side. Yet sadly we've heard it all before.

Check out this track: Her older brother Michael may have made a similarly titled classic, but on "Rock With U," the younger Jackson offers her own version for club DJs and house fans.
