The Best and Worst Singles of the Week -- From Fifth Harmony to Spandau Ballet

Billy Currington
"Don't It"
Mercury Records

"Baby, don't say no so quick/This ain't about me trying to see how far that I can get," the ever-smooth Billy Currington purrs on "Don't It." The country charmer makes a convincing case: Promises of dancefloors, karaoke bars, the moon and the stars are wrapped up in a raucous '80s radio-rock package of banjos, guitars and huge live drums. --Jill Menze

Fifth Harmony Live: Watch 'Bo$$' Performance & New Song 'We Know'

Fifth Harmony
"Sledgehammer"
Epic Records

Fifth Harmony's second offering from its upcoming debut is already known as "the single written by Meghan Trainor," who nailed this girl-group track. With an EDM-meets-new-wave beat and an immediate hook, "Sledgehammer" is the best pop track about the physical effects of lovesickness since Demi Lovato's "Heart Attack." --Jason Lipshutz

K. Michelle Talks 'Rebellious Soul' Success & Upcoming Solo VH1 Show

K. Michelle
"Maybe I Should Call"
Atlantic Records

K. Michelle has supplanted Keyshia Cole as R&B's most versatile emotional firestarter, and for "Maybe I Should Call," the second single off her second LP, Anybody Wanna Buy A Heart? (due Dec. 9), she furthers her case. Bristly and raw, the song smartly balances her serrated yelp with tender lyrics about a lover's absence. --Steven J. Horowitz

Baauer's 'Harlem Shake': Billboard Cover Story

Baauer Featuring AlunaGeorge and Rae Sremmurd
"One Touch"
LuckyMe Records

He'll be forever remembered for the meme miracle that was "Harlem Shake," but Baauer's latest, a beast of a single with a soulful R&B kick, shows he's no flash in the pan. "No Flex Zone" rap duo Rae Sremmurd gets hysterical, but Aluna Francis' eerie swoon is what sells this stunner. --Dan Hyman

Check Out AlunaGeorge's Brand New Track 'Supernatural'

Spandau Ballet
"This Is The Love"
Rhino Records

Thirty years after Spandau Ballet's last U.S. single, the British new-wave quintet brings back everything that made it danceable on "This Is the Love," touting a thick sax, Tony Hadley's syrup-and-silk delivery and poppy drum work. The twist? There's also a James Bond theme vibe mixed in. --Andrew Flanagan

Ingrid Michaelson Embraces 'Intellectual Poppiness' on 'Lights Out' Album

Ingrid Michaelson
"Afterlife"
Cabin 24/Mom+Pop/Red

Michaelson emjoyed a revival this year with the Billboard Hot 100 mainstay "Girls Chase Boys" and has moved on to her next snappy paean, letting an earworm whistle melody take the lead. "Afterlife" lacks the bite of its predecessor, but with its life-affirming (if slightly mawkish) lyrics, expect to hear Michaelson's latest in an inspirational TV ad or two. --Jason Lipshutz

Charlie Wilson Talks New Uptempo Album & Recording With Kanye West

Charlie Wilson
"Goodnight Kisses"
RCA Records

Uncle Charlie continues his decades-long smooth streak with "Goodnight Kisses," his latest satin-lined single. Over snap-and-swing doo-wop-inspired production, the Gap Band co-founder sings sweetly about his loved one's smooches. At 61 years old, Wilson is still as convincing a romantic as ever.  --Steven J. Horowitz
