ocarina of time had the best music in any game imho
Ahh Chrono Trigger is pretty awesome too. As for the FF games, I'm torn between FFVI and FFVII.Yeah, but did it have music so good that it was sampled for a Wiz Khalifa song, or led to a remix mashup album of Jay-Z songs? I think not!
(original full OST here)
FFVIII would probably be my second favorite. Morrowind is pretty good, too.
Only soundtrack that I have ever listened to outside of a game, Diablo II.
