Thanks for the suggestion! It's the workflow part I'm worried about. 😄 I was kinda thinking a git would be perfect: different branches are different versions or styles of the song, versioning is taken care of, and probably other benefits I can't even dream of. But my friends won't be staging and committing. I also haven't done this in a while, so it'll be cool to see what others may know about.
You may have just saved my marriage with this one 😄
