"Let Your Conscience Be Your Guide" is the debuting single for singer Marvin Gaye, released as Tamla 54041, in May 1961. It was also the first release off Gaye's debut album, The Soulful Moods of Marvin Gaye, in which most of the material was the singer's failed attempt at making an "adult" record compared to Motown's younger R&B sound.
