The team of Shinji Miyazaki and Masafumi Mima (the sound director, for anyone wondering) was responsible for such utterly embarrassing music ****ups like putting the XY Legendary battle theme over Pierre and Aria's introductory dance in "Party Dancecapades!",
Perhaps a bit excessively over-hype-y but not even remotely comparable to playing an apocalyptic track over a zero-stakes battle against a wild Pokémon.
using the Meloetta Song over the kiss and Litten's training in SM007 (seriously, what the ****?!),
Not tonally inappropriate for a romantic moment
or a heartwarming moment of bonding between a young Pokémon and its mentor-slash-father figure.
putting Future Connection--a fast-paced song--over that slow-paced montage of Dewpider trying to find a new pond,
Not tonally inappropriate for a montage of a Pokémon going on its own little adventure. Also a song that Shinji Miyazaki had no involvement with. I will grant that Mirai Connection was used as an insert song way too often, but all the people who likely would have been involved with making that decision?
Still on the show.
and oh let's not forget about that absolutely ****ing horrid circus music playing over Mewtwo taking everyone's Pokemon
Will you kindly stop with the italicized bolded red letters? It bleeds into the forum background in a rather unpleasant way. Also an example from over 20 years ago. Also ignoring entirely that the intent of that track was to convey panic and confusion and a general sense of disarray, and that as that exact scene went on the music got more tense as the stakes became more personal (aka, as Mewtwo caught more and more of our heroes' Pokémon and singled in on Pikachu who was actively resisting capture). Am I saying that there was nothing wrong with the music in that scene? Not really, it
did feel kinda goofy. But you are
seriously overplaying how unfitting it was. In fact I would argue the
remake's track is arguably a worse fit by being in full doom-mode from the get-go. Heck, the first few notes are
more ominous than the music during Pikachu's chase scene (and even the later fight between the clones and the originals, you know, the part that's
supposed to be horrifying?). Also from what I have heard from composers describing how the workflow of composing for movies or video games or such things tends to work, it's likely that this scene only sounded the way it did because
Kunihiko Yuyama requested that kind of music. Though you are right that evidently someone, be that Yuyama, Mima or Miyazaki, later decided that that piece wasn't really a good fit, so... I'll give you that one.
So yeah. Not a single one of your examples are anything even remotely comparable to playing an outright apocalyptic piece over a battle to get a backpack back from a mischeivous wild Pokémon. Heck, I struggle to think of a single piece of music in the show's rotation for as long as I've been watching that's even
been that ominous. And again you are disregarding that what music goes where in any given episode
wasn't up to Miyazaki, and that the people in charge of making that decision would still be the exact same even if Miyazaki was still working on the show. So they likely would have picked a piece with a similar tone. Something like "Catch Pidgey?!" from M20, perhaps. Or a new piece written for this show, idk, in this hypothetical alternate world where Miyazaki was still composing it's still
possible that they would decide to wipe the musical slate entirely clean and start over with only new compositions even though I see no good reason why they would do this.
