Fuck What You Think is the second and final album by Canadian/American hip hop group Main Source. It was released by Wild Pitch Records in March 22, 1994, and it was shelved after Main Source broke up later that year. However, the album was re-released as a CD and double LP in 1998. Large Professor, one of the group's founding members, left the group before the making of this album.
On this album, Sir Scratch and K-Cut combined their talents with Mikey D, an emcee previously signed to Sleeping Bag Records, who demonstrates a raw voice and delivery. The song "Set It Off" includes verses from Jadakiss and Sheek Louch of D-Block before they became successful a few years later. In addition, there is a female emcee named Shaqueen (Kool G Rap's wife) who contributes to "Set It Off" and "Fuck What You Think." Only one single was released from the album, "What You Need" in 1993.
