Rihanna vs. Britney Spears – Pop Clash

After a close race, Rihanna and her Navy managed to sink Miley Cyrus' latest release 'We Can't Stop' into the Pop Clash abyss. This means RiRi and her newest, David Guetta-featured single 'Right Now' will go champion onto another round of our weekly fan-voted song battles!

This week, RiRi will take on another pop queen, her former 'S&M' remix partner, Britney Spears. Although it's not her own album single, Brit is back in the spotlight with her bubbly soundtrack song for 'The Smurfs 2,' entitled 'Ooh La La.'

With the release of 'Right Now,' we see Rihanna taking a break from the ballad beat she's been on ('Diamonds,' 'Stay') for something a little more uptempo and danceable. She recruited her pal David Guetta, whom she previously collaborated with on 'Who's That Chick?,' for the 'Unapologetic' song, and the bumping club track has the French DJ's name written all over it. Over the swelling, dubstep-tinged electro beat, RiRi sings, "Tomorrow way too far away / And we can't get back yesterday / But we young right now / We got right now / So get up right now / Cause all we got is right now."

Meanwhile, Britney Spears, who is still riding high on the success 'Scream & Shout' with will.i.am, is returning to her bubblegum roots with her catchy, bouncing 'Smurfs' single 'Ooh La La.' The midtempo, dance-pop track finds Brit getting coquettish, as she purrs, "Ooh my my baby don't be shy / I see that spark flashing in your eye / My heart beats fast 'cause I want it all / So baby come with me and be my ooh la la." Spears also gets super sassy on the heavier pre-chorus, where she gets a little hip-hop on all y'all with her in-your-face vocal delivery.
