Beyonce - Run the World (Girls)

In November 2010, Knowles revealed that she had begun work on her fourth studio album, 4, and was writing and producing new material. She explained that she was using live music to create her own music genre. She later clarified the statement, "Well, I wouldn't say I'm inventing a new genre… I'm mixing every type of genre that I love and I'm inspired by every type of genre… It's not R&B. It's not typically pop. It's not rock. It's just everything I love all mixed together in my own little gumbo of music." Knowles revealed that the album was inspired by several musicians, including Fela Kuti, The Stylistics, Lauryn Hill, Stevie Wonder and Michael Jackson. Producers and songwriters working on the album include Jim Jonsin, Ne-Yo, Sean Garrett, The Dream, Symbolyc One, Diplo, Switch, Derek Miller and Frank Ocean. 4 will be released on June 28, 2011. Its lead single, "Run the World (Girls)" was released on April 21, 2011.
