"Go!" is the third single from the Common album Be. It is produced by Kanye West, who also performs backing vocals for the track alongside John Mayer. The track's percussion is handled by Num Amuntehu, while its scratches are provided by A-Trak. Its beat contains a sample from "Old Smokey" by Linda Lewis. Its lyrics deal with sexual fantasies.

Two remixes of "Go!" featuring Joy Denalane were released as singles: one was remixed by Kanye West and the other by Jazzanova. J. Cole also raps over the "Go!" beat on "Knock On Wood Freestyle" on his The Blow Up mixtape.

Common, Kanye West and John Mayer were inspired to create a song after seeing the 2004 movie Ray. They all headed to a studio where Kanye worked on a beat and Mayer told Common to write about fantasies. Despite Common's initial hesitance of being influenced by a non hip hop artist, he wrote the song and it was later recorded in two studios: Sony Music Studios in New York City and Encore Studios in Burbank, California.

It was the most commercially successful song on Be as it reached #79 on The Billboard Hot 100 and also reached the Hot R&B/Hip-Hop Singles & Tracks and Hot Rap Tracks charts. Critics attribute this success to its mellow beat, smooth vocals and subject matter. Spence D. of IGN.com writes:
