"Maria (I Like It Loud)" is based on the 2002 rework of the song "I Like It Loud" by Marc Acardipane feat. Dick Rules. The original song is written by Marc Acardipane and was released in 1997 under the name "Marshall Masters feat. The Ultimate MC". The single version of "Maria (I Like It Loud)" was released under the name "Scooter vs. Marc Acardipane & Dick Rules" and both Marc Acardipane and Dick Rules have appeared in the music video.
"Weekend!" samples "Weekend" by Earth & Fire as well as "Strange World" by Push (aka M.I.K.E.), and "America: What Time Is Love?" by The KLF. The music video is based on the music video by The KLF. Three versions of the music video were released: censored (or UK video), uncensored and the X-rated video.
"The Night" samples both Italiandisco star Valerie Dore's hit 1984 single, "The Night" and "Magic Impulse" by Exposure. The song is probably inspired by Jay Frog's remix of the song released as "Planet Trax Remix" on the 1997 CD single "The Night" by Valerie. Two versions of the music video were released: censored video (or UK video) and uncensored video.
"Roll Baby Roll" samples the ABBA song "Arrival", taken from the 1976 album of the same name. It was replaced on later issues of the album (including "20 Years Of Hardcore" expanded edition) with the song "Swinging in the Jungle" with the different melody due to copyright violations. However, in 2008 Scooter performed "Roll Baby Roll" with the original melody by ABBA live in Berlin. The song appeared in the live stream by the VIVA TV channel, but was not included in the DVD version of the concert released as the part of the Jumping All Over The World album. In 2014 "Roll Baby Roll" was performed again during the "20 Years Of Hardcore" tour, but there were neither livestream nor official video of the tour however.
"Level One" samples the song "Freedom" by Chris Hülsbeck, the ending theme of Turrican II, and is probably inspired by the song "See You In The Next Life" by Atlantis ITA.
"Liquid Is Liquid" is the rework of the same name song by Liquid and also includes elements of the song "The Second Trip (DJ Scot Project Mix)" by Hennes & Cold.
"A Little Bit Too Fast" samples the song "I Am Rushin'" by Bump.
"Siberia" samples taken from Turkish Folk Song "Hüma Kuşu" performed by Devrim Kaya (on the "20 Years Of Hardcore" expanded edition).
