No, no sound/music. Here's the use-case:
I right click on "MewnBase" then click Open (To get past the silly Apple message since its not installed from their appstore)
Then the window shows up with a black screen. After a few seconds I get the loading umbrella of doom icon that spins for what I'm guessing is indefinitely.
