"Run the World (Girls)," the lead single from Beyonce's forthcoming fourth album, is set to hit iTunes tomorrow (Apr. 21) after a full version of the song leaked on Monday.
The song -- originally thought to be titled "Girls (Who Run the World)" -- will also make its radio debut tomorrow morning at 8:00 am EST. "Run the World," which uses a sample of Major Lazer's "Pon De Floor," was co-written by Terius "The-Dream" Nash and Beyonce, and produced by Switch with additional production by Beyonce and Shea Taylor. Diplo, who serves as Switch's partner in Major Lazer, is not credited on the song.
Before "Run the World (Girls)" officially premieres, Beyonce has released a 17-second teaser trailer for the song. The short clip shows a trio of stark images -- a barbed wire fence as dawn breaks, a broken-down car with the word "Revolution" painted in red, and a crumpled-up newspaper -- before the pop star appears on top of a horse.
