"I can't listen to this. It's Video Game music and needs to be in a game"

Everytime I hear Mako's reactor anywhere, which is a normal piece from FF7, my blood runs like crazy and I become all happy. However, if I hear some good pieces from Atelier series, I think they're good music and I really enjoy them, but the feeling I have with Mako's reactor is not there.
I do listen to VGM outside the games, but only for games that I know I'll never play, or will play in a long time away. Like Rydia and Summonmaster said, I don't want to "spoil" the games by listening to its music first, because when it come to the scenario contains the music that I know, my feeling is like "ok, good piece, it fits, nice, what next." I hate when things like that happen.

Jam it back in, in the dark.
