"Since I Had You" is a quiet storm-styled soul song recorded by singer Marvin Gaye for the I Want You album. The song was co-written by Gaye and producer Leon Ware and is a song that, like "All the Way Round", talked of a reunion between the singer and a reputed lover, this time at a dance floor and convincing the woman despite the fact their relationship has cooled into a friendship to make love again. Like "Come Live with Me Angel" and "Feel All My Love Inside" before, the song includes sexual moans.
