The Nemesis music just has something about it. It captures all the things in the backstory so well, the anger, agression, sadness and tradgedy, it's so magnificently composed.
The Oblivion music is the similar, it captures what the ride is about. I love the way there are numerous versions of it with different lengths, and that each one has it's own version of the video syncronised to it. It works well with what the ride is about and it's theme, especially the part where the video says Worlds...First...Verticle...Drop...Roller...Coaster...Oblivion.
Air again is similar in the way it captures the meaning of the ride.
