    The lead single for her 7th studio album “Femme Fatale,” this is pure electro-pop. The opening beat is punchy; imagine a Guetta anthem slowed down a notch. Just like her last single “Hold it Against Me,” the new single is fun and doesn’t require much thinking to enjoy. The track was written by Ke$ha and Dr. Luke and produced by Max Martin.

    7. Ke$ha, “Blow”

    8. Diddy-Dirty Money featuring Skylar Grey, “Coming Home”

    9. Chris Brown featuring Lil Wayne & Busta Rhymes, “Look at Me Now”

    10. Jeremih featuring 50 Cent, “Down on Me”
