Rocky Steps: The 72 stone steps before the entrance of the Philadelphia Museum of Art, in Philadelphia, Pennsylvania, have become known as the "Rocky Steps" as a result of their appearance in the triple-Oscar-winning film "Rocky" and all of the series' sequels except for "Rocky IV", in which the eponymous character runs up the steps to the song "Gonna Fly Now".  Tourists often mimic Rocky's famous climb, a metaphor for an underdog or an everyman rising to a challenge.  A bronze "Rocky" statue was briefly situated at the top of the steps for the filming of "Rocky III".  This statue, now located at the bottom right of the steps, is a popular photo opportunity for visitors.  The top of the steps offers a commanding view of Eakins Oval, the Benjamin Franklin Parkway, and Philadelphia City Hall.

Food Chain (EP): In contrast to Danielsen's previous solo album "Enjoy the Process", which featured only the singer along with his acoustic guitar," Food Chain" featured a full band.  In October 2014, prior to the release of the EP, the singer released "Rescue Me", the second song from the album via Revolver Magazine.  The singer stated that he selected the tune, because "it’s a very powerful song that a lot of people can relate to in this day and age", going on to say that "We live in an overly medicated society, and we all have people close to us being affected".

Sensualité: "Sensualité" is a 1993 song recorded by the Belgian singer Axelle Red.

Gonna Fly Now: "Gonna Fly Now", also known as "Theme from "Rocky"", is the theme song from the movie "Rocky", composed by Bill Conti with lyrics by Carol Connors and Ayn Robbins, and performed by DeEtta West and Nelson Pigford.  Released in February 1977 with the movie "Rocky", the song became part of American popular culture after main character Rocky Balboa as part of his daily training regimen runs up the 72 stone steps leading to the entrance of the Philadelphia Museum of Art in Philadelphia and raises his arms in a victory pose, while the song plays.  The song was written in Philadelphia.  The song is also often played at sporting events, especially at sporting events in the city of Philadelphia or featuring sports teams from there.

The band achieved its greatest success in the 1980s, producing many charting singles, especially in the United States.  The band is best known for its double platinum-certified 1982 hit "Eye of the Tiger", the theme song for the motion picture "Rocky III" (US number 1 for 6 weeks).  Singles like "Burning Heart" (US number 2), "The Search Is Over" (US number 4), "High on You" (US number 8), "Is This Love" (US number 9) and "I Can't Hold Back" (US number 13) continued to chart in the mid-1980s.

Man Against the World: "Man Against the World" is a song by American rock band Survivor.  It was the fourth track and the third single released from their 1986 album "When Seconds Count".

The song did appear as a bonus track on the 2006 reissue of the "Rocky IV soundtrack" album, along with Survivor's two other Rocky-related singles - the #1 hit "Eye of the Tiger" (the smash hit from "Rocky III") and "Burning Heart," which was the song ultimately chosen for the "Rocky IV" soundtrack and peaked at #2.

Nobody Else (CeCe Peniston song): "Nobody Else" is a 1998 song by CeCe Peniston.  The composition was to be the lead single of the singer's originally scheduled album release on the Silk Entertainment label, as well as reportedly released on Steve Hurley's compilation "The Voices of Life, Vol 1."  The production of her album was cancelled eventually, and releasing of the compilation wouldn't happen either.  However, the singer released another two singles on the label, "He Loves Me 2" the following year and "My Boo" in 2000.

Eye of the Tiger: "Eye of the Tiger" is a song by American rock band Survivor.  It was released as a single from their third album "Eye of the Tiger" and was also the theme song for the film "Rocky III", which was released a day before the single.  The song was written by Survivor guitarist Frankie Sullivan and keyboardist Jim Peterik and was done so at the request of "Rocky III" star, writer, and director Sylvester Stallone, after Queen denied him permission to use "Another One Bites the Dust", the song Stallone intended as the "Rocky III" theme.  The version of the song that appears in the movie is the demo version of the song.  The movie version also contained tiger growls, something that did not appear on the album version.  It features original Survivor singer Dave Bickler on lead vocals.
