New music: Willow Smith – I Whip My Hair

Willow Smith is nine years old. Let me repeat that. Willow Smith is nine years old. She's also the daughter of Will Smith and Jada Pinkett Smith, and the sister of Jaden, 12, star of the recent Karate Kid remake. If you can ignore the fact that she's only NINE YEARS OLD, I Whip My Hair is a pretty good R&B belter in the same vein as Rihanna, all heavily treated vocals and huge juddering beats. Lyrically, there's mention of getting one's "swag on" and "just tryin' have fun so keep the party jumpin'". We're assuming that's jumping up and down on a bouncy castle with all your other nine-year-old friends buzzing off too much Dr Pepper, right? Move over Justin Bieber, you're too old for all this.
