Question: Which artist collaborated with Verse Simmons in the song "Man Down" ? 

<P0-S0> "Man Down" is a song by Barbadian singer Rihanna from her fifth studio album, "Loud" (2010). <P0-S1>  Singer Shontelle and production duo Rock City wrote the song with its main producer, Sham. <P0-S2>  They wrote it during a writing camp, in Los Angeles of March 2010, held by Rihanna's record label to gather compositions for possible inclusion on the then-untitled album. <P0-S3>  Rock City were inspired by Bob Marley's 1973 song "I Shot the Sheriff" and set out to create a song which embodied the same feel, but from a female perspective. <P0-S4>  "Man Down" is a reggae murder ballad which incorporates elements of ragga and electronic music. <P0-S5>  Lyrically, Rihanna is a fugitive after she shoots a man, an action she later regrets. <P0-S6>  Several critics singled out "Man Down" as "Loud"' s highlight, while others commented on her prominent West Indian accent and vocal agility. <SEP> <P1-S0> "The Entertainer" is a single by singer Billy Joel released as the only single from his 1974 album "Streetlife Serenade". <P1-S1>  The song peaked at #34 on the US charts, a Top 40 hit for Joel that year. <P1-S2>  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". <P1-S3>  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." <P1-S4>  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). <P1-S5>  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. <P1-S6>  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. <SEP> <P2-S0> Nigerian recording artist and music producer Slim Burna has recorded a total of twenty three songs including remixes, covers and guest features. <P2-S1>  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. <P2-S2>  In 2009, he released his own version of "Oyoyo" (originally by J Martins) which helped gain him some attention. <P2-S3>  The song became a hit record, appearing on several mix albums put together by the Nigerian DJs Coalition. <P2-S4>  He collaborated with award-winning Nigerian rapper M-Trill on the song "Oya Na", which was duly released in May 2012. <P2-S5>  The following month, Burna released "I'm on Fire" and hinted towards a new mixtape. <P2-S6>  He later confirmed through a video footage that he had begun work on his debut project. <P2-S7>  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. <P2-S8>  Bukwild contributed to the songwriting and delivered the second verse of the track. <P2-S9>  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. <P2-S10>  His first full length project "I'm on Fire" was released on April 11, 2013. <P2-S11>  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. <SEP> <P3-S0> Maurice "Verse" Simmonds is a Puerto Rican American singer, songwriter, and record producer. <P3-S1>  Based in Los Angeles California bit raised in the Virgin Islands, he moved to the United States after high school and he formed the production duo the Jugganauts in the 1990s. <P3-S2>  The duo has since co-written and produced tracks such as "Man Down" by Rihanna and "Who Gon Stop Me" by Kanye West and Jay-Z, both of which charted prominently on "Billboard".
