Question: Who contributes the sole guest verse on Jay-Z's album that includes the song "Song Cry"?
Context: "Is That Your Chick (The Lost Verses)" is the second single from Memphis Bleek's second album, "The Understanding".  The single version featured Jay-Z and Missy Elliott.  The album version featured a verse from Twista and another verse from Jay-Z.  The song was produced by Timbaland and was released in 2000.  The original version of the song appeared on the European (but not American) version of Jay-Z's "Vol.  3...Life and Times of S. Carter".  Memphis Bleek later recorded verses for the song, and it was released as the second single from Bleek's "The Understanding".  In the alternate version the chorus is changed from ""Cause that's Jay and them..." to "Cause that's Bleek and them..."". "1, 2 Pass It" is a collaboration song by the one-shot The D&D All-Stars, a group consisting of Doug E. Fresh, Fat Joe, Jeru the Damaja, KRS-One, Mad Lion, and Smif-N-Wessun.  Produced by DJ Premier, it is the only single from the album "The D&D Project".  Each emcee gets his own verse, excluding Tek and Steele of Smif-N-Wessun, who share a verse.  Lyrics from Fat Joe's verse were later sampled and used in the chorus of Jay-Z's "Bring It On", and Pharoahe Monch's Intro of his album Internal Affairs.  A Line from Smif-N-Wessun's verse was used on the chorus of Jay-Z's "So Ghetto," produced by DJ Premier.  A line from Jeru's verse was later used on his own song "Scientifical Madness". "Back Like That" is the second single by rapper Ghostface Killah from his critically acclaimed fifth solo album "Fishscale".  The song features R&B singer Ne-Yo and has become Ghostface's highest charting solo single on the Billboard Hot 100.  It contains a sample of "Baby Come Home" as performed by Willie Hutch as well as "Song Cry" by Jay-Z.  A remix featuring Kanye West & Ne-Yo was produced and later included on Ghostface's sixth album "More Fish".  In 2009, Ghostface performed the song with Chrisette Michele at VH1's 6th Annual Hip Hop Honors ceremony. "The Entertainer" is a single by singer Billy Joel released as the only single from his 1974 album "Streetlife Serenade".  The song peaked at #34 on the US charts, a Top 40 hit for Joel that year.  The song is a cynical and somewhat satirical look at the fleeting fame of a musician and fickle public tastes ("Today I am your champion / I may have won your hearts / But I know the game / You'll forget my name / And I won't be here / in another year / if I don't stay on the charts"); this theme would be examined in the later song "It's Still Rock and Roll to Me".  Another verse in the song references the shortening of Joel's song, "Piano Man", from 5 minutes and 38 seconds to 3 minutes and 5 seconds to fit a radio slot, referenced by the lyrics "It was a beautiful song, / but it ran too long / If you're gonna have a hit, you gotta make it fit / So they cut it down to 3:05."  Additionally, the timing printed on the label of the 7" release of "The Entertainer" was 3:05, although the actual 45 length was 3:11 (while the album length was 3:41).  In the single version, Verse 3 (which starts at 1:02 in the album version) is edited out, and Verse 2 (which starts at 0:40) contains a steel guitar in its second half, which is actually featured in the second half of the "third" verse in the album version; indeed, on the single mix, the instrumental crescendo of the album version is anticipated by bringing the fuller instrumentation of Verse 3 under the vocals of Verse 2.  As a result of this, the slightly emptier original instrumentation of Verse 2 (which includes a downward slide on the synth) and the vocals of Verse 3 are completely omitted, while the instrumentation of Verse 3 (featuring the steel guitar) does appear, but earlier. Nigerian recording artist and music producer Slim Burna has recorded a total of twenty three songs including remixes, covers and guest features.  After he quit his production job at Grafton Records in 2008, he formed Street Rhymes and has since made beats and created music in his own studio.  In 2009, he released his own version of "Oyoyo" (originally by J Martins) which helped gain him some attention.  The song became a hit record, appearing on several mix albums put together by the Nigerian DJs Coalition.  He collaborated with award-winning Nigerian rapper M-Trill on the song "Oya Na", which was duly released in May 2012.  The following month, Burna released "I'm on Fire" and hinted towards a new mixtape.  He later confirmed through a video footage that he had begun work on his debut project.  The second single released from the tape was "All Day" which Burna recorded with some vocal assistance from fellow Garden City singer Bukwild Da Ikwerrian.  Bukwild contributed to the songwriting and delivered the second verse of the track.  Burna also collaborated with P.I. Piego, a member of Hip hop group Ruud Boiz, on the third single "Claro", released on February 8, 2013.  His first full length project "I'm on Fire" was released on April 11, 2013.  Later that same year, Burna also contributed a guest verse to the song "Bad Girl" for Young Paperboyz's second studio album, "Naija Boss Techno Reloaded" and released the song "Oh Na Na Na" in commemoration of Nigeria's 53rd Independence Day Anniversary, which ultimately became the first top ten hit of his career. "Heavy Metal Kings" is a single by hip hop duo Jedi Mind Tricks, released in 2006 through Babygrande Records.  The single was released in a limited edition blue vinyl pressing, with every copy signed by group vocalist Vinnie Paz.  "Heavy Metal Kings" is the lead single from the group's fifth album, "Servants in Heaven, Kings in Hell".  The song features a sample from "Boiling Rage (Estuans Interius)" by German composer Carl Orff, taken from his famous cantata "Carmina Burana", and a vocal sample from "Front Lines (Hell on Earth)" by Mobb Deep for the chorus.  "Heavy Metal Kings" features a guest verse from former Non Phixion member Ill Bill.  The song's music video was released shortly before the album's release, and featured guest appearances from the group's DJ, DJ Kwestion, and R.A.  The Rugged Man. "1990-Sick (Get 'Em All)" (AKA: "1990-Sick (Kill 'Em All)") is a 1995 song by Spice 1.  It originally appeared on the album of the same name.  The song features a guest verse from fellow West Coast rapper MC Eiht.  The song would go on to reach #91 on the Billboard Hot R&B/Hip Hop Singles & Tracks chart and #18 on the Hot Rap Singles chart.  Due to extreme amounts of profane language and violent content in the lyrics, the lyrics in the music video version for "1990-Sick" are heavily altered, to the point where the lyrics are unrecognizable when compared to the original uncensored album version.  A version of the song without MC Eiht was also made and included on the "1990-Sick" album.  The song would be released as a 12-inch single on October 30, 1995.  The song would later appear on Spice's 1998 greatest hits album "Hits". "Song Cry" is a song by American rapper Jay-Z and produced by Just Blaze.  It was the fourth and final single from his sixth studio album "The Blueprint" and also appears on the 2001 live album "". Fall Down is a song written and recorded by the American rock band Tantric.  The song was originally recorded for the shelved ""Tantric III"" album, but due to leaving Maverick Records in 2006 the band released the song on their official Myspace page in May 2007 featuring a guest verse by the American country-rap group Nappy Roots, due to the band leaving their label and the original lineup collapsing the song remained unreleased.  In November 2008 due to demanding popularity by fans the band re-recorded the song for a deluxe version of their album The End Begins but without the verse from Nappy Roots.  The song was officially released as the third and final single from The End Begins on November 8, 2008. The Blueprint is the sixth studio album by American rapper Jay-Z, released on September 11, 2001, by Roc-A-Fella Records and Def Jam Recordings.  Its release was set a week earlier than initially planned in order to combat bootlegging.  Recording sessions for the album took place during 2001 at Manhattan Center Studios and Baseline Studios in New York City.  Contrasting the radio-friendly sound of Jay-Z's previous work, "The Blueprint" features soul-based sampling and production handled primarily by Kanye West, Just Blaze and Bink, as well as Timbaland, Trackmasters and Eminem, who also contributes the album's sole guest verse.
