A.e.r.o. - Flying Through The Universe is one of the best music in my opinion.
For some reason, in 0.9.8.0 (actually since 0.9.7.4), this music won't play in game. It's supposed to be the first music when I play it in order. But the next music becomes the first. Is it a bug or something it's supposed to be. This file is in my music folder, only that it would just not play.
