That is quite possibly the most commercially overused piece of music ever composed, and I am so utterly fucking sick of hearing it.
They use it for trailers, movie screenings, runway shows. It's EVERYWHERE. It's pretty much stock music at this point, so you shouldn't be surprised to hear it over something like that.
I contest your opinion that it was a "good choise". Lux Aerterna has become the new "Eye Of The Tiger".
Granted it wasn't
as overused during SW's production, and was only meant to be placeholder music to give Michael Bross an idea of what kind of musical atmosphere Lorne and crew were looking for. It wouldn't have been in the final game. If it was, I might have had to drive out to Lorne's house and kill him in his sleep.
