It's probably impossible to replace the BGM of each game with an mp3 of your choice, but I was wondering if there was a way to mute the music and play whatever song you want, probably in WMP or something. I know there's a null-sound option, but I'd really like to keep the sound effects intact, and only mute the music. If this is actually possible, let me know.

Why don't you replace the BGM of the game with empty sound files? But I'm not sure if it's possible for every game though. It depends on the file formats and such.

How would you go about doing that? If I could replace the BGM files in the first place, couldn't I replace them with songs of my choice?
