"Doesn't Really Matter" is a song by American singer Janet Jackson from the soundtrack to the 2000 film Nutty Professor II: The Klumps and her seventh studio album, All for You (2001). It was written and produced by Jackson, Jimmy Jam and Terry Lewis. The track was sent to contemporary hit radio in the US on May 23, 2000, after an unmastered version was leaked to several radio stations. It is an upbeat electropop, R&B and dance song with a syncopated drum loop and bassline. Based on a previously discarded poem Jackson wrote, the lyrics are about her film character's love for The Nutty Professor.
