Beyoncé: 'Run The World (Girls)'

It's easy to forget that Beyoncé's last album I Am... Sasha Fierce was released back in 2008. Heading it up with the double A-side 'If I Were a Boy'/'Single Ladies', she went on to release a mammoth seven further cuts from the LP in various corners of the planet, each as single-worthy as its predecessor. Ready with solo album mark four, can its trailer succeed in the exceptionally tough job of jump-starting the "B Revolution"?

Earthy beats, hypnotising hooks and militant drums pound relentlessly as Queen B declares it's "GRLZ who run this mutha" with more woman-friendly conviction than Geri Halliwell at a Spice Girls convention circa 1998. With no identifiable structure, the uber-trendy, uber-squiggly Major Lazer 'Pon De Floor' sample - a staple on the underground scene since 2009 - is free to roam as it sees fit; adding up to an aggressive, head-spinning and ferocious club stomper that doesn't quite fulfill the task in hand, but it's not for want of trying.
