Released on 22 May 2006, it was the band's last single before their five-year disbandment later that year.  The song is written from the perspective of a man who has cheated on his girlfriend with another woman.  He tells his now angry girlfriend in the first verse that the other girl meant nothing to him.  In the second verse he admits that the relationship is over and his once girlfriend is now his ex.  The music video for the song is inspired by the film "Flashdance".  The song was a disappointment, only charting at #39 on the UK Singles Chart.  This was the band's lowest charting single since 2003 single "Get Your Hands off My Woman".

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.

Man Down (song): "Man Down" is a song by Barbadian singer Rihanna from her fifth studio album, "Loud" (2010).  Singer Shontelle and production duo Rock City wrote the song with its main producer, Sham.  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.  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.  "Man Down" is a reggae murder ballad which incorporates elements of ragga and electronic music.  Lyrically, Rihanna is a fugitive after she shoots a man, an action she later regrets.  Several critics singled out "Man Down" as "Loud"' s highlight, while others commented on her prominent West Indian accent and vocal agility.

Natalia Keery-Fisher discography: The English singer-songwriter Natalia Keery-Fisher has released two studio albums, two extended play (EP), and seven singles as an artist, as well as four as a featured artist, and thirteen music videos.  She began her musical career by releasing a standalone single, entitled "Don't Play Nice", under the alias of Verbalicious, with label All Around the World.  Although the song reached number eleven in the United Kingdom, the label went bankrupt shortly after the song's release.  In 2008, Sinclair collaborated with French recording artist M. Pokora in the song "They Talk Shit About Me", as Verse.  Sinclair later changed her stage name to Natalia Cappuccini and released the extended play "Wommanequin" independently.

The Entertainer (song): "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.
