Straight from the Lab is a 2003 bootleg album consisting of previously unreleased songs by Eminem. Some of the songs on the album were scheduled to be released the following year on Eminem's fifth studio album, Encore.
If those hadn't leaked, Encore would've been a much different album. "We as Americans", "Love You More", a lot of songs ended up on the bonus disc because they leaked and that disappointed me. So, I had to start over, which felt like a mountain I had to climb. You climb half the mountain, and then all of a sudden, you get knocked back down. "We as Americans" was going to start the album, then "Bully". "Evil Deeds" was in there. If that would've been on Encore, and the other couple songs that leaked, to me it would've been right there with The Eminem Show as far as its caliber.[3]
"Hailie's Revenge" (sometimes referred as "Doe 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.[4][6]
"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.[3] The version in the bootleg is the original uncensored version, with the bonus disc version having a line about the president reversed, while this one does not.
"Love You More" (incorrectly titled "I 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.
A second mixtape, titled Straight from the Lab Part 2, leaked in 2011 consisting partly of unreleased songs from the shelved 2007 album, King Mathers.[7]
"Things Get Worse" was later released on B.o.B's Greatest Hits album. In 2019 the track leaked again with a never-before-heard verse,which caused so much controversy around it, that Eminem had to apologize to Rihanna for it
"Going Crazy" (later mastered and retitled "Fame") was later released on D12's 2011 mixtape, Return of the Dozen Vol. 2.
