Question: So Far... was a song that contained a sample of the lead single from which other Eminem album?
Context: American rapper Nicki Minaj has recorded songs for three studio albums, one re-issue and three mixtapes, some of which were collaborations with other performers.  Her debut album, "Pink Friday", was released in November 2010. " Your Love" was released as the lead single; it contains a sample of British singer-songwriter Annie Lennox's song "No More I Love You's".  Minaj wrote the songs "Roman's Revenge" (which features American rapper Eminem) and "Here I Am" in collaboration with producer Swizz Beatz.  "Roman's Revenge" references both artists' alter-egos, Roman Zolanski for Minaj and Slim Shady for Eminem.  She co-wrote the song "Did It On'em" with Grammy Award-winning American producer Bangladesh, alongside Justin Ellington and Safaree Lloyd Samuels.  Minaj and J. R. Rotem worked together on the seventh and eighth single releases "Girls Fall Like Dominoes" and "Fly", which features Bajan recording artist Rihanna.  On "Girls Fall Like Dominoes", Minaj raps about how she can steal fans from male artists in the music industry, specifically Lil Wayne and Drake.  Rihanna's contribution to the "inspirational" ballad "Fly" was added at Minaj's request, as noted by Jayson Rodriquez writing for MTV News.  Andrew "Pop" Wansel and Warren "Oak" Felder co-wrote three tracks with Minaj, including "Your Love", "Save Me" and "Muny". "Encore" (stylized as "ƎNCORE" and sometimes known as "Curtains Down") is a song by rappers Eminem, 50 Cent and Dr. Dre, released in 2004 as a vinyl single in the U.S.  It was the title track from the Eminem album of the same name, which was also released that year.  It is the third single and final track from the album. "I Want Your Love" is a song by Atomic Kitten, released as the third single from their debut album "Right Now".  The single peaked at number 10 on the UK Singles Chart, and also reached number 48 in Ireland.  The song heavily samples the theme to the 1958 film "The Big Country".  Almost exactly a decade earlier, the same sample had been used on the song "The Only Rhyme That Bites" by MC Tunes vs 808 State, which also peaked at number 10 on the UK Singles Chart.  Initial copies of "I Want Your Love" contained a sample of the KLF's 1991 hit single "Justified and Ancient"; later copies had the sample removed.  The video & radio versions contained vocals from Kerry Katona; these vocals were replaced on the album version by Jenny Frost.  The song was produced, arranged, recorded and mixed by Damien Mendis at Metropolis Studios, London.  "I Want Your Love" is also featured on the "Greatest Hits" album. "The Real Slim Shady" is a song by American rapper Eminem from his third album "The Marshall Mathers LP" (2000).  It was released as the lead single a week before the album's release.

It was released as the lead single from "Encore", and was later included on his greatest hits compilation album "" (2005).  The song caused controversy as its lyrics and music video parodies Michael Jackson, who was being accused of child molestation at the time.  The song also pokes fun at Beavis/Cornholio, MC Hammer, Madonna, and others.  It also heavily spoofs Pee-wee Herman, going as far as imitating his signature shout during the chorus and Eminem dressing like him in the video.
