* ''Series/BabylonFive'' made a point of deliberately doing this every season, to reflect the changing mood of the show. The [[https://youtu.be/Bhc_Oem8Whc second season theme]] was a souped-up revamp of the [[https://youtu.be/BtrUhIuEqdY first season theme]], the [[https://youtu.be/d9EbGd1AlMg third season theme]] kept the same musical style but was a different and much darker piece altogether, the [[https://youtu.be/2w560Q8ELOg fourth season theme]] combined elements of the season two and season three themes into a bombastic, militaristic take on the original theme, and the [[https://youtu.be/oxdLult6YKU season five theme]] was something completely different again but with thematic elements of all the earlier themes. The TV movies and [[Recap/BabylonFiveTheLostTales01 The Lost Tales]] likewise had their own themes that copied stylistic elements of the main ''Babylon 5'' themes but were themselves original pieces.

* ''VideoGame/SonicTheHedgehogSpinball'' was originally going to use a remix of the ''VideoGame/SonicTheHedgehog1'' theme for its own title. Creator/SegaTechnicalInstitute only figured out on the ''literal'' last possible day that [[ScrewedByTheLawyers the copyrights didn't actually work out that way]], and hastily created a new theme tune -- so hastily that a tiny percentage of carts managed to make it off the production line and into stores with the original theme intact.

* Disney decided to dub the remaining Digimon movies that had stayed in Japan. When it came to dubbing [[Recap/DigimonAdventure02M2RevengeOfDiaboromon the 02 movie]] and both ''[[Recap/DigimonTamersM1BattleOfAdventurers Tamers]]'' [[Recap/DigimonTamersM2TheRunawayDigimonExpress movies]], however, they didn't have the rights to "Digimon are the Champions" as their theme, as the first three seasons were dubbed for Creator/FoxKids before Disney acquired the rights to the franchise. Instead, they had to use the ''Anime/DigimonFrontier'' theme (and associated score, for that matter) across all [[Recap/DigimonFrontierMovieIslandOfLostDigimon four]] movies.

* ''Series/MarriedWithChildren'', throughout its entire run, used Frank Sinatra's "Love and Marriage" as its theme tune. The later DVD releases and some (though oddly not all) modern syndicated repeats replaced it with a cheery, soulless instrumental soundalike which lacks the irony and charm of the original piece. This was even a problem in the reunion special made in the early 2000s, though at least they used an instrumental of "Love and Marriage" there.

* Speaking of ''WesternAnimation/LooneyTunes'', the early years of the series would often switch themes ([[RearrangeTheSong ignoring how many times "The Merry Go Round Broke Down" and "Merrily We Roll Along" were modified]]). It wasn't until 1937 that ''Looney Tunes'' got it's familiar "The Merry Go Round Broke Down" theme, and 1936 when ''Merrie Melodies'' switched to "Merrily We Roll Along".

* ''Series/WheelOfFortune'' used an Alan Thicke tune called "Big Wheels" until 1983, when it was ousted for the show's most iconic theme, "[[https://www.youtube.com/watch?v=wf37Dgj92QM Changing Keys]]", composed by show creator Creator/MervGriffin. "Changing Keys" was re-orchestrated several times in 1989, 1992, 1994 and 1997 (with Merv having little to no hand in the last two remixes) until the theme was finally retired in 2000 for "Happy Wheels" by Steve Kaplan, with THAT theme reorchestrated in 2002 by Kaplan and 2006 by Frankie Blue and John Hoke (after Kaplan's untimely death)...[[UpToEleven and THEN changed out in 2017]] for an unnamed, rather-generic theme by Hoke, [[BookEnds only for the iconic "Changing Keys" to return in late 2021]], this time done up by Bleeding Fingers Music, to the fandom's surprise.

* The original ''Series/V1983'' changed its theme tune a number of times during its run.

* ''Series/TopOfThePops'' changed its theme tune several times during its 42-year run as a weekly series. Its best known theme is "Whole Lotta Love", though it wasn't introduced until 1970, six years after the series started. Also, contrary to popular belief, the version used wasn't the Music/LedZeppelin version, but a cover version by CCS. In 1981, following a period in which the series had a TitleOnlyOpener, "Whole Lotta Love" was replaced by "Yellow Pearl" by Phil Lynott, which was itself replaced by "The Wizard" by Paul Hardcastle in 1986, followed by "Now Get Outta That" by Tony Gibber in 1991, then "Red Hot Pop" by Vince Clarke in 1995. In the late 1990s and early 2000s, a remixed version of "Whole Lotta Love" was used, with "Now Get Outta That" receiving the same treatment from 2003 until the end of the weekly series in 2006.

* Sometime around 1981, ''Series/TopOfThePops'' changed its theme from the long-standing adaptation of Music/LedZeppelin's ''[[https://www.youtube.com/watch?v=omWD9sdoEWY Whole Lotta Love]]'' that had been there almost since the start, to [[https://youtu.be/S0CFTQkaY1U something blander and more anodyne and "in keeping with the eighties'']]. It was if they were saying "If you remember the old theme tune, piss off, you're too old".

* The ''Franchise/{{Gundam}}'' franchise mostly follows this to a T bar a few exceptions: all the shows from Anime/MobileSuitZetaGundam to Anime/TurnAGundam had two different openings which would change around the halfway mark of the show (the only exceptions to this were the aforementioned '' Turn A Gundam'' and Anime/MobileSuitGundamWing which debut their second openings pretty late, both at Episode 41 of the respective show) and shows starting from Anime/MobileSuitGundamSEED would have 4 openings that would change roughly every 13 episodes or so (the exception to this was Anime/GundamReconguistaInG which was a two-cour anime so it only had two openings).

* ''Series/TheTwilightZone'' originally had a dreamy theme by Music/BernardHerrmann - the one everybody knows didn't come along until season two, when CBS decided it needed something more upbeat. Herrmann wrote two alternative themes which weren't used, and Music/JerryGoldsmith wrote one which was also turned down; CBS music head Lud Gluskin then put together two short tracks written by Marius Constant, and the rest is history (ironically, Constant was never credited with the theme on the show).

* Sometime around 1981, Series/TopOfThePops'' changed its theme from the long-standing adaptation of Music/LedZepellin's ''[[https://www.youtube.com/watch?v=omWD9sdoEWY Whole Lotta Love]]'' that had been there almost since the start, to [[https://youtu.be/S0CFTQkaY1U something blander and more anodyne and "in keeping with the eighties'']].
