If Sonic is R&B and Swing, Mario is clearly Big Band Jazz, fo sho. The Megaman franchise is the Heaviest Metal (before Guilty Gear's grungy butt rock was realized on the Playstation), but also a bit of Synth Pop for the lighter.
Final Fantasy is Classical Symphony, but in terms of sounding like something from a Movie/Show? One thing I heard was that Nobuo Uematsu was really inspired by the soundtrack to the 1984 "Never Ending Story" composed by Klaus Doldinger. Specifically, the song "Bastian's Happy Flight" Sounds eerily close to some of the Airship themes from Final Fantasy II onward (Highwind takes to the skies being the closest).
I also did a review for the Parasite Eve movie on my channel, where I ended up getting a copyright claim for a song I used. Though, it wasn't for anything I put into the video, but the soundtrack of the movie used in a clip from the film itself. No probs, the copyright holder allows for his shit to be played on Youtube. But the benifit was, I got to figure out who the composer of the movie was, beign a one Joe Haishi (who is a major contributor to Ghibli movie soundtracks).
I bring it up here, because as I was watching them movie, I kept thinking of the music from the game. But the movie came out in 1997, before the PS1 game. But the movie was so popular, it convinced the Japanese populace that mitochondria are green, so I'm betting money on the fact Yoko Shimomura was trying to ape the movie's OST for the game.
