"Go!" is the third single from rapper Common's sixth 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.

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 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:

Common may refer to:

In music, a song is a composition for voice or voices, performed by singing. A song may be accompanied by musical instruments, or it may be unaccompanied, as in the case of a cappella songs. The lyrics (words) of songs are typically of a poetic, rhyming nature, though they may be religious verses or free prose.

A song may be for a solo singer, a duet, trio, or larger ensemble involving more voices. Songs with more than one voice to a part are considered choral works. Songs can be broadly divided into many different forms, depending on the criteria used. One division is between "art songs", "pop songs", and "folk songs". Other common methods of classification are by purpose (sacred vs secular), by style (dance, ballad, Lied, etc.), or by time of origin (Renaissance, Contemporary, etc.).

A song is a piece of music for accompanied or unaccompanied voice or voices or, "the act or art of singing," but the term is generally not used for large vocal forms including opera and oratorio. However, the term is, "often found in various figurative and transferred sense (e.g. for the lyrical second subject of a sonata...)." The noun "song" has the same etymological root as the verb "to sing" and the Oxford English Dictionary (OED) defines the word to mean "that which is sung" or "a musical composition suggestive of song." The OED also defines the word to mean "a poem" or "the musical phrases uttered by some birds, whales, and insects, typically forming a recognizable and repeated sequence and used chiefly for territorial defence or for attracting mates."

Kanye Omari West ( /ˈkɑːnjeɪ/; born June 8, 1977) is an American musician, film director and fashion designer.
