"Are You That Somebody?" is a song performed by American R&B recording artist Aaliyah, recorded for the Dr. Dolittle soundtrack (1998). The song was co-written and composed by Static Major, who also sang backing vocals, and Timbaland, who, in addition to writing the song, produced and performed a guest rap for it. The song was sent to U.S. pop radio stations on September 29, 1998 (see 1998 in music). The song samples the sound of a baby cooing from producer Jac Holzman's 1964 track "Happy Baby" from Authentic Sound Effects Volume 8 (later used in Perrey and Kingsley's 1966 hit "Countdown at 6" off The In Sound from Way Out!) and also samples The Meters' 1974 single "People Say".
