Animals were definitely on the prowl last week. Kesha's devoted fans voted her newest 'Warrior' single, 'C'Mon,' into the About to Pop winner's circle. Kesha's hungry legion of listeners will be pleased to know that 'C'Mon' will receive 20+ spins on PopCrush's radio show this weekend! Check out a list of stations where you can tune in by clicking here.

With a new week upon us, it's time for a fresh quintet of About to Pop hopefuls. Pink is leading the competition this week with her third single off of 'The Truth About Love,' her collabo with fun. frontman Nate Ruess, 'Just Give Me a Reason.' Although Ruess was hesitant about cutting a track with the pop powerhouse, Pink is obviously very convincing, and the duo's vocals blend harmoniously as they sing about mending a broken relationship on the simple piano ballad.

Pink is followed by newcomer Nikki Williams, a South African transplant that we recently had the pleasure of watching perform live, and holy hell, does this girl bring it. Her new single 'Glowing' shows off her vast vocal range, spanning from delicate, high notes to booming, powerful belting. The love song also delivers a building, blood-pumping, synth-pop beat that will make you want to get up and cut loose on the dance floor.

Just like the aforementioned nominees, the rest of the artists in this week's fan-voted competition is a mix of old and new musicians.

Veteran rockers Green Day are up for their ¡Tré! single 'The Forgotten,' a softer, piano-rock ballad that also appears on the 'Twilight Saga: Breaking Dawn - Part 2' soundtrack. Meanwhile, British chanteuse Jessie Ware made her breakthrough in the U.K. this year, and she's become an obsession of ours here in the States too. Ware's soulful vocals sounds beyond gorgeous on her glossy, drum-driven single 'Wildest Moments.' And closing it all out are alt hit makers Lifehouse and pop songbird Natasha Bedingfield. They teamed up to sing about conquering the odds on the band's new single 'Between the Raindrops,' a moody, pop-rock track that also boasts some country flair.
