This practice occurs when the soundtrack to a movie, TV show, or video game is different when re-released. This can be due to numerous factors, though licensing costs is often a big reason.
- Common for anime which is made for a younger audience; western composers will often create their own soundtrack for the series, throwing out the Japanese soundtrack. One Piece is a controversial example, though Bruce Faulconer's 1999 score for Dragon Ball Z has its fans.
- Dragon Ball Kai is another example, with Kenji Yamamoto (who did the music for the DBZ video games) composing a replacement soundtrack. However, during the Android Saga it was discovered that Yamamoto had plagiarized music from other sources (and had been doing so for years), he was fired and the original Shunsuke Kikuchi soundtrack from DBZ was reinstated for the rest of Kai.
- Castle in the Sky is both an example and a subversion; when it was initially released in North America, it had an entirely different score than the original version. When it was re-released in 2010, the original Japanese score was reinstated. The 2017 re-release allows the viewer to choose either score.
- Inevitable for silent movies, as the film stock doesn't have a soundtrack to begin with. Many of them did have custom musical scores provided for the live musical accompanists to play along the movie as a soundtrack of sorts, but most of those have been lost to time.
- Bill Cosby: Himself featured a different opening (and thus, different song) when released on DVD.
- Top Dog: In a scene where a group of clowns terrorize Jake's house, some over-the-top circus music plays. In the DVD release, this is replaced with generic music from composer George S. Clinton.
- Happy Birthday to Me's original DVD from Sony Pictures had a completely different, disco-inspired, soundtrack, to the annoyance of fans. It was later revealed that the film's temp soundtrack was used accidentally. Anchor Bay's DVD reissue and Mill Creek's Blu-ray have the original audio.
- When the first three syndicated seasons of Baywatch were released by Fremantle/First Look, all the licensed music (including the iconic theme song) was thrown out and replaced by other songs.
- A frequent victim is Top Gear. The original BBC run contains a running gag in which whenever the guys are given the task of making over their cars, it will be accompanied by the A-Team theme. Due presumably to costs, the repeats on the Dave channel replace this theme with a variety of mediocre tunes.
- The original SNES version of Donkey Kong Country 3: Dixie Kong's Double Trouble! was composed by Eveline Fischer; when re-released for the GBA, David Wise created an entirely new soundtrack.
- Sonic the Hedgehog CD: The original Japanese soundtrack was kept for the European release, but the American version replaced it with a whole new soundtrack for some reason. However, some of the original tunes were kept, which led to a rather jarring problem: each stage had its main theme and three remixed versions, but the American soundtrack only replaced the main version and two of the remixes, leaving the remaining one sounding nothing like its accompanying tracks. When the game was rereleased in 2011, all regions used the original Japanese soundtrack by default, but included the option to use the American tracks.
- Teenage Mutant Ninja Turtles: Turtles in Time: The original arcade and SNES music was replaced with a new soundtrack on the Mutant Nightmare version, and the HD remake Re-Shelled also featured a brand new soundtrack.
- When The Simpsons: Bart vs. the Space Mutants was re-released on Sega Genesis, it had a completely new soundtrack. Notably, it didn't feature The Simpsons theme song like the NES version did.
- Mr. Nutz (SNES, Mega Drive) had different music when it was ported to the GBA.
