Definitely.
Personally, they need to patch both 2D & KR with all of each other's music (some tracks are only in one or the other), and make them all music box gears (not to mention correcting the ages-old typo in the 2D music cfg file).
Maybe we'll see this for SA...
Oh, and Devs - remember, you promised to make "The Wanderer" music box gear and "The Redeemer" sword available later, through means other than the Book of Truth quest - now's the time....
