Yes, while I am a little disappointed, this is nothing new for people that collect soundtracks from films either, lol. They ALWAYS leave stuff off, very rarely is a release complete. And there is some very good music in the game that isn't even influenced by Williams that I also really like that is all Jared's creation. Still, I understand legal issues and the like when it comes to Williams material. But yes... I hope there will be other ways to listen to the music also heard in-game. But people should still appreciate what we got because there are some good bits there, and the sound quality seems better than the game files.
And it is funny that even though the available soundtrack is just released in alphabetical order, it actually DOES have a well-rounded listening experience to it when I played it all the way through! Didn't expect that either, lol!
