"Do Somethin'" is a song by American recording artist Britney Spears from her first greatest hits compilation, Greatest Hits: My Prerogative. It was released on February 14, 2005 by Jive Records as the second single from the album worldwide except North America. Produced by Bloodshy & Avant, the song was never intended to be released as a single and Spears had to convince her record company to shoot a music video for it. "Do Somethin'" is a dance-pop song with usage of electric guitars. Lyrically, it refers to having a good time and not caring about other people's judgement.
