>>23349562from a purely musical standpoint the Mystery Dungeon tracks are objectively more complicated than the majority of the Main series music. thematic devices are all over the place that give the music more relevance to the story and gameplay than "oh lol 8th gym city better make it super dramatic"
the exception is Viridian City for this and you know very well why and the only two generations that are up to par are IV and V musically. VI has terrific production values but tries too hard
sorry Matsuda and I and II (even the remakes) are simple to the point of being able to deduce each one down to the T in terms of Music Theory.
I hope you've played the mystery dungeon games, otherwise your dislike of the soundtrack would be unfounded as there are reasons why certain melodies and progressions are used consistently.
