Wild 9 is one of my favorite games for the PlayStation, and a big reason is the music I thought was particularly well done. Much to my glee I could also stick it into my PC and record the soundtrack right off the game disc! Is there a list of other such games for the PS1, or perhaps you have a story about your fun soundtrack discovery? Happy holidays!
[EDIT]
Alright, in an attempt to grow out collective video game libraries, I'll compile an ever-evolving list here. If this topic is already hiding somewhere on the formuns, someone point us to it!
