Rocks Off's handy Google alert tells us that a new Beyonce single, "Girls (Who Run the World)" - or at least a demo - leaked onto the Internet sometime in the past 24 hours. Apparently Ryan Seacrest's L.A. radio show played the track, which seems to be audio from the Michael Jackson-esque video shoot (above), and a few blogs noticed.

You know, just a few. Here's what they're saying:

New Beyonce!!!: "It´s just a demo but we like it! It reminds us of classic Destiny´s Child. Like a 2011 Lose My Breath!" PerezHilton.com

"It leaked! And there's a lot going on." Vulture

"Set to a marching beat which samples Major Lazer's 'Pon de Floor,' pop's fearless leader wields her power over the opposite sex." Rap-Up

"According to a few fans sites and twitter pages, this is the unfinished demo version, and all I can say is 'I hope so.'" Necole Bitchie

Bey Sting!: "Sounds like she's going the Euro-dance hall route that's a big trend right now." The Young, Black & Fabulous

"Beyonce taps into Willow Smith's girl-power awesomeness to offer a grown-up anthem for all of the women who are confident, independent, and oh so sexy." Clutch Magazine

"Twitter has showed me that Beyonce fans can inflict cruel and unusual punishment if you go against Bey so I won't dare mention that I don't like this track, oops." The Hood Nerd

She always keeps things fresh and innovative, and Beyonce Knowles' new single "Girls (Who Run the World)" is no exception. " The Gossip Girls

Beyonce Rips Off Own Songs For New Hit: "While Sony are yet to confirm whether Girls is the official new single and when the finished version will be released, the leaked demo version copped a cyber flogging when it dropped on Tuesday morning." Daily Telegraph

Rocks Off: Eh. Doesn't do a whole lot for us. Still, it's got to be better than "Whip My Hair," right?
