“Turn Off the Light” is a song by Canadian singer-songwriter Nelly Furtado, taken from her debut studio album, Whoa, Nelly! (2000). Written by Furtado, and produced by Gerald Eaton, Brian West, and Furtado, the song was released as the album’s second single in mid-2001 (see 2001 in music). Furtado, who cited a song by the Canadian band Big Sugar as the inspiration for “Turn Off the Light”, has described it as “a real song … Though I may seem so independent and stuff, blah, blah, blah, when I turn out the light at night I can get lonely just like everybody else. Maybe that’s why it’s such a good song and everyone is responding to it – because it’s real. Just a song with a fun, hooky chorus.
