As one of the world's most popular DJs, David Guetta is well known for his room-moving turntable skills. But the French electro-house maestro is equally impressive at rocking a Rolodex. On Nothing but the Beat, the follow-up to his 2009 breakthrough, One Love, Guetta collects A-list cameos the way LMFAO order shots: Nicki Minaj, Usher, Chris Brown, Snoop Dogg, and Ludacris are all here, as are One Love alum Akon and will.i.am, who introduced Guetta to American audiences when he hired him to co-produce the Black Eyed Peas' 2009 anthem ''I Gotta Feeling.'' Even the gettin'-slizzard chick from Far East Movement's tipsy '10 smash ''Like a G6'' shows up.
So what does Guetta do with this star power? Little you haven't heard before: Like Jersey Shore gone to Italy, Beat employs a fresh setting to make a familiar point namely, that dancing to high-energy disco grooves shares quite a bit with having sex. (See: ''Turn Me On'' and, um, ''I Just Wanna F- - -.'') Guetta warms up on ''Night of Your Life,'' a fiery future-soul number with Jennifer Hudson, and on the pep-talk closer, ''Titanium,'' which contains a triumphant vocal turn by quirk-pop kook Sia. Those are rare flashes of heart, though, on an album that ultimately feels colder than its sweat factor suggests. B–
