Quoted from iceman44:
Terrible communication. Par for the course.
Why wouldn't you have open source code to allow swapping out the songs?
Just like I don't want to go to a restaurant and cook my own dinner, I don't want to spend $9000 on a pinball machine then have to put my own sound in.
For those who have done it, if you put the sound in yourself, how well integrated can it be to the gameplay?
