"Steal My Sunshine" is a song by Canadian band Len, co-written by band member Marc Costanzo and featuring on their third album You Can't Stop the Bum Rush. The backdrop is based on a sample of a short instrumental portion of Andrea True Connection's 1976 disco single "More, More, More". Supposedly inspired by The Human League's 1981 synthpop hit "Don't You Want Me", the song's vocals alternate between Marc and Sharon Costanzo. Mumble C (Marc Costanzo) produced the track. Gregg Diamond, who was given songwriting credit as the original composer of "More, More, More", died three months before the album was released.
