I have always enjoyed soundtracks, and music from video games. Especially if I had spent any significant amount of time playing them in my childhood, or other significant or traumatic times in my life.

I spent many days throughout my life listening to midi files way back, I bought OST's for FFXI in like 2005 on CD when it was a little harder to get that kind of thing.

I had some final fantasy vinyls, and other music stuff for OSTs that were lost in my moves and etc.
