Xenoblade Chronicles, easily. Really not a competition. Imported the 4-disc OST from Japan…one of the greatest purchases I've ever made, outside of the game itself.
Super Mario Galaxy 1 and The Legend of Zelda: Skyward Sword would be in the top 3 from 7th gen for me.
Honorable mention to The Last Story soundtrack, too.
