A game that came to my mind for me when it comes to being shitty but has probably the best soundtrack setlist in the series is Megaman X6, arguably one of the worst Megaman game in comes to gameplay and difficulty, but one thing that makes it crazy is the soundtrack, it’s varied and they slap much harder than even the first Megaman X
Not shitty per se but I didn’t like Magic Carpet. Russell Shaw’s in game music was pure magic though.
