Does anyone know any video game music that highly resembles other music, gaming or not? I know Mega Man music sounds like a lot of oldies music, such as the level select for Mega Man 1 sounding like bits of a Journey song.

There's also Bionic Commando (NES) and The Last Ninja 3 (C64)

It's probably just coincidence, but 0:10 of the Bionic Commando music sounds really close to 0:11 of The Last Ninja 3 music.
