Any game that Jeremy Soule has worked on has an absolutely amazing soundtrack. Some of my favorites are from the Guild Wars and Elder Scrolls franchises. Guild Wars 2 is probably my favorite of the bunch though despite my not actually liking the game.
Final fantasy music is very memorable. It's very well made and of course the repetitiveness has something to do with it too. I'm just happy that it's good music so at least you don't mind hearing it many times over and over.Final Fantasy 7 and 11 soundtrack, Metal Gear solid 2. Very nice in my opinion.
