Totally agree!! He was in the band...your friend...and belongs to ALL of you...(not your "real" question's answer but...)
Don't let him dfegad all over you like that...or say fuuck , too bad, and just up and
I'd

on over there and

those songs out of him
Then

one with him, because you ARE still bandmates.
Point being, he should at least copy them on a drive for the rest of you.
