Jessie J, ''Domino''
We still don't know exactly who Jessie J is (a sassy rock diva? The British Katy Perry?), but Dr. Luke has the cure for her identity crisis: one bubbly club beat, an injection of disco keyboard drama, and a gauzy hook about dancing in the moonlight. It still might not be the real her, but it makes us put our hands up. A- Kyle Anderson
Snow Patrol, ''Called Out in the Dark''
The Irish quintet, who first skyrocketed to fame when their ''Chasing Cars'' appeared on Grey's Anatomy, return with this bright, atmospheric tune. While it's not melancholy enough to hit that nighttime-soap sweet spot, ''Dark'' brings more pop to Patrol's rock vibe, and wraps it all in one heck of a catchy chorus. B+ Tanner Stransky
Lady Antebellum, ''We Owned the Night''
In their post-''Need You Now'' career, the trio have tended toward snoozy piano-laden pop, but rootsy vocals and a sprightly mandolin melody drive energy into this return-to-form country romance from their forthcoming Own the Night. B+ Grady Smith
Nicole Scherzinger, ''Don't Hold Your Breath''
The former Pussycat Doll's zillionth (approx.) attempt at breaking into pop divadom is a pretty good shot: There's a fiery kiss-off to the world's worst ex, and a soaring chorus that reaches a 7.25 on the Sing It With Your Just-Dumped Girlfriends on the Dance Floor meter. But is it gonna make her the next Britney? Scherzinger's right: Don't hold your breath. B Melissa Maerz
Alice Cooper, ''I'll Bite Your Face Off''
The snotty swagger and chugga-chugga-blues licks (from the veteran shock rocker's upcoming Welcome 2 My Nightmare) are pure Sticky Fingers-era Stones. He may have moves like Jagger, but the horror-movie chorus proves Alice is still very much himself. B KA
One Direction, ''What Makes You Beautiful''
And you thought boy bands were dead. This shallow but crushworthy love ditty from the British-Irish fivesome top 10 finishers on England's X Factor last fall shows the genre still has a (dreamily coiffed) pulse. B+ TS
