Just throwing this out there but Music could probably wait until after an early access release, right? Who's with me?
I mean people who play DF are so particular that I can't imagine many of them starting up DF and getting lost in the immersive soundtrack.
You get lost in the management of details, while listening to your own music perhaps.
Just trying to justify a quicker release date because I'm itching to try the new menus. :)
