So I have some gift cards to burn and was hoping to pick up some/all of the LOTR soundtracks and it seems there are plenty o' options to choose from...should I get the 3 cd set? (which I assume is missing content from the limited editions of each film that are available separately) Is the only way to get the "supertrailer" in the ROTK limited version? And if I had to choose just one, I've heard several opinions that say TTT is the best of the 3....ahhhhhhhhh! Overwhelmed! Thanks guys!
