Straight from the Lab

Straight from the Lab is a 2003 bootleg album consisting of previously unreleased songs by Eminem. The songs on the album were scheduled to be released the following year on Eminem's fifth studio album, Encore. It's speculated that the album was leaked by Eminem's brother, Nathan "Nate Kane" Samara-Mathers. Since its release the album has been repackaged by numerous counterfeiters, with most including bonus tracks.

Songs

 * "Can-I-Bitch" samples Slick Rick's song "Children's Story" in the first verse. It is also a word play on the title of Canibus's first album, entitled Can-I-Bus being a diss track to Canibus and is an answer song to the Pet Shop Boys' 2002 song "The Night I Fell in Love".
 * "Bully" is a diss track aimed at rappers Benzino, Irv Gotti and Ja Rule.
 * "Hailie's Revenge" (sometimes referred as "Do Rae Me"), is another diss track which features vocals from Eminem's daughter Hailie Jade in the intro and the outro. It is a response to Ja Rule's song "Loose Change", in which Ja Rule has insulted Eminem's family, including Hailie.
 * "We as Americans" (incorrectly titled "We Are Americans") was later included on a bonus disc for Eminem's fifth studio album, Encore. In 2022, Eminem stated that if the song had not leaked, it would have been the opening track on the album, followed by "Bully" as track two.
 * "Love You More" was also included on the Encore bonus disc.
 * "Come on In" (later retitled "6 in the Morning") was later released on D12's sophomore album, D12 World.
