I agree 100% Alderaan is such a tease. I can't tell you how many times I've enjoyed the music on the loading screen, only to be left in silence 5 minutes later. I really like the score on many worlds, but it feels like they almost never play when I need it. I've resorted to playing a mix-set of classic star wars in the background.
I felt the same way about the Balmorra theme back in beta. Why do you hardly ever hear it? Such a waste.
