Our picks for the 10 tunes you're sure to be blasting on the beach and rocking at the barbecue.
BLACK EYED PEAS, ''I GOT A FEELING''
This Euro-style electro banger promises even bolder body-moving than lead single ''Boom Boom Pow,'' already a No. 1 smash.
KATY PERRY, ''WAKING UP IN VEGAS''
What happens in Vegas apparently stays on the pop charts. The ''I Kissed a Girl'' singer's glitter-bombs-and-guitars ode to Sin City hedonism is her fourth single from 2008's multiplatinum One of the Boys.
LIL WAYNE FEAT. KEVIN RUDOLF, ''IN YOUR FACE''
Wayne forsakes his misguided sidetrack into singing on his latest track, spitting clever rhymes alongside a preening hair-metal hook from Rudolf.
KID CUDI, ''DAY 'N' NITE''
It's been floating around the blogosphere for more than a year, but the Ohio-born MC's hypnotic insomniac's tale is finally, deservedly, finding mainstream success.
3OH!3, ''DON'T TRUST ME''
Another grassroots grower, this Colorado joke-hop duo's gleefully misogynistic anthem tempers cringe-y couplets (''Don't trust a ho/Never trust a ho'') with a soaring ''woo woo'' chorus.
KRISTINIA DEBARGE, ''GOODBYE''
Dad James danced to the beat of the rhythm of the night as a member of '80s R&B family DeBarge, but 19-year-old Kristinia reaches further back to sports-stadium staple ''Na Na Hey Hey Kiss Him Goodbye'' in her stomping pop rebuff.
THE GOSSIP, ''HEAVY CROSS''
Überproducer Rick Rubin helms the triumphant return of the cult blues-punk trio; a thumping ''Edge of Seventeen'' bass line explodes into a fierce dance-floor track.
SHINEDOWN, ''SECOND CHANCE''
Every summer needs its shamelessly histrionic, big-blast-chorus crossover from the modern-rock charts; Shinedown win this year's (booby?) prize.
Ultrasmooth Parisian pop-disco le synth, c'est chic! that in a perfect alternate universe would share the airwaves with the likes of Flo Rida.
LADY GAGA, ''LOVEGAME''
She commanded us to ''Just Dance,'' then showed her ''Poker Face.'' Now the outré club diva aims for a third No. 1 with her selfless offer to ''take a ride on your disco stick.'' Will you let her?
