About to Pop: Justin Timberlake, Bruno Mars + More Singles

Congrats to last week's winner, Marina and the Diamonds, who won by a landslide! Their single 'How to Be a Heartbreaker' garnered 82% of the votes -- so expect to hear the sizzling pop confection on this weekend's Top 20 Countdown radio show. The list of stations where you can tune in are posted here.

In this week's About to Pop, we highlight two of pop music's leading crooners who ooze sexiness. After a seven year (!!!) hiatus, Justin Timberlake brings sexy back (or does he?) with his new Jay-Z assisted single 'Suit & Tie.' We were thrown off by the down tempo intro, but the '70s groove and JT's signature falsetto keep us going back for more. We think people might feel the same, which could garner some radio play this week.

Alternately, Bruno Mars shows his sexiness, albiet vulnerable, in his new piano ballad 'When I Was Your Man.' The lyrics of the recently 'Jimmy Kimmel'-performed song have Mars pining over a lost love. We love a guy who can show his sensitive side.

JT and Bruno have stiff competitive, however, as fun.'s third single 'Carry On' (off their Grammy-nominated album 'Some Nights') is gaining traction. Meanwhile, Nelly's making a comeback in 2013 with his guitar-laden single 'Hey Porsche' (off his seventh studio album), and Britt Nicole makes a return on our list with her love song ‘Gold.’

So who will get your vote? Listen to JT, Bruno, fun., Nelly and Britt, and vote for your favorite every hour until the poll closes on Jan. 21 at 3PM EST. Good luck!
