Not so sure about that... Git would let you do something like this, and if the tracks are separately stored, you could pick and choose commits, and fork, branch, merge, etc.

git branch newleadsinger

git commit -m "added new main vocal track"

git commit -m "trying new drum track"

git commit -m "guitar track moved up a key"

git commit -m "more cowbell"

git commit -m "less cowbell"

git commit -m "deleted cowbell track"

git commit -m "added echo to vocal track"
