Lady Gaga, ”The Edge of Glory”
Gaga’s inventory of ’80s throwbacks now includes an anthem that could have been swoon fodder for a Top Gun montage. Her voice shines, though Clarence Clemons’ sax gets buried in pop afterburn. B+ — Christian Blauvelt

Avril Lavigne, ”Smile”
Pink took Lavigne’s title as the go-to for potty-mouthed pop angst a while back, which is why this Max Martin-produced shouter sounds a little lightweight despite its crisp uppercut of a chorus. B- —Kyle Anderson

Jordin Sparks, ”I Am Woman”
Though the sixth-season Idol winner tries her best for a female-empowerment dance-floor banger, she fails to launch a revolution with her repetitive beats and puddle-deep lyrics. C+ —Tanner Stransky

David Guetta feat. Nicki Minaj & Flo Rida, ”Where Them Girls At”
Mix French DJ Guetta’s synthy overload with woo-hoo-laced guest spots by both Flo and Nicki. Add sun and sand, and voilà! The ideal early-summer party jam. B+ —Tanner Stransky

Jason Derülo, ”Don’t Wanna Go Home”
Derülo is less an artist than a magpie; he builds his latest on a manic, incongruous mix of Robin S.’ 1993 club classic ”Show Me Love” and Harry Belafonte’s ”Day-O (The Banana Boat Song).” But his knack for picking and packaging shiny bits of pop detritus somehow still works in his favor. B- —Leah Greenblatt

Nicole Scherzinger feat. 50 Cent, ”Right There”
The ex-Pussycat invites Fiddy to frolic on her own personal Scherzy Shore, purring come-ons in a vaguely Caribbean patois; he RSVPs with a laconic ”Yes, please.” B —Leah Greenblatt

Simple Plan feat. Natasha Bedingfield, ”Jet Lag”
Bedingfield lends her shiny pipes to a loud and surprisingly lovely pop-punk pounder about intercontinental relationships. With the next blink-182 album still MIA, this will do just fine. B+ —Kyle Anderson
