"Deep Cover", also known as "187", is the debut single by Dr. Dre's and his first track released after the breakup of N.W.A. The track was recorded for the soundtrack of the film Deep Cover. The song features Snoop Doggy Dogg making his first appearance on record.

The album peaked on the Billboard 200 albums chart at #166 on July 25, 1992. Apart from the soundtrack compilation, it also appeared as a single and on Dr. Dre's First Round Knock Out, which spent two weeks on the Billboard 200 starting at #52 and later on several greatest hits albums, including: Doggy Stuff and Doggy Style Hits. Like the artist indication on the original 12" vinyl says, "Dr. Dre introducing Snoop Doggy Dogg", it is the first time Snoop Dogg was featured on a record. As a single it had no major breakthrough regarding sales, but it launched Snoop Dogg's career. It samples a number of 1960s, 1970s, and 1980s funk acts, such as Undisputed Truth's "(I Know) I'm Losing You" and Sly & the Family Stone's "Sing a Simple Song", which provided the drumbeat. The single was set to be released on The Chronic, but fallout from Body Count's banned song, "Cop Killer", prevented it since this song is also about killing police officers. Despite being praised by critics, the film itself did not have much commercial success, and it only received two nominations on the Independent Spirits Awards in 1993; however, the song was well received. The song was featured in the video game Grand Theft Auto: San Andreas, on the radio station Radio Los Santos. During the 2007 VH1 Hip Hop Honors show, T.I. and B.G. performed this song during Snoop's honor ceremony. In April 2012 at the Coachella event in California, Snoop and Dre performed the song live.
