It's been a couple of weeks since our last About to Pop competition, but our most recent winner was newcomer Nikki Williams! Her single 'Glowing' garnered an overwhelming 65% of the fan votes before the holidays, beating out artists like Pink and Green Day for a spot on PopCrush's nationwide radio show -- a proper congrats is in order for Ms. Williams and all of her fans! 

The first About to Pop competition of 2013 will see Rihanna, Jessie J plus more artists going head-to-head for 20+ spins on PopCrush's weekend radio countdown. The 'Unapologetic' songstress is in the running with her David Guetta-produced single 'Right Now,' a blood-pumping, club jam will get you dancing and pumped for the New Year. Meanwhile, Jessie J fans can vote on her midtempo, R&B love ballad 'Silver Lining (Crazy 'Bout You...),' from the acclaimed film 'Silver Linings Playbook.'

But RiRi and Jessie aren't the only singers you can vote for, as Marina and the Diamonds, Olly Murs and Mike Posner are also competing. Marina's Diamonds will have the chance to  teach 'How to Be a Heartbreaker' if they can secure the win, while Olly Murs lovers can vote for the catchy crooner's 'Troublemaker' track, featuring Flo Rida.

Finally, in the wake of the tragedy that occurred in Newtown, Conn. on Dec. 14, singer-songwriter Mike Posner wrote the touching tribute 'Heaven' for the victim's family, our last song in this week's About to Pop.

Listen to all of the nominated singles below and vote for your favorite once per hour until the poll closes on Jan. 14 at 3PM EST. Good luck!
