I have a feeling that each world won't use the same field theme for every area, such as the Toy Story world. If the field theme was a remix of "You Got A friend In Me", it would fit for Andy's room and the outside area, but it doesn't seem to fit for the Toy Store. "You Got a Friend In Me" sounds I guess Western, Country, I don't know how to describe it, which fits for Andy's room, but the Toy Store looks futuristic and Sci-Fi, but that's my opinion what do you guys think.
