Continuing the discussion from edit #56018268.
Work A was written by Artist A.
Artist B made a “cover”, which is different enough to be a new work, Work B. Should Artist A be credited as a songwriter for Work B, which they did not write anything new for or is the Work B is based on Work A relationship sufficient?
And if we credit songwriters of based on works to new works, where do we draw the line?
Artist Z wrote Work Z which samples Work Y by Artist Y, which in turn samples Work X by Artist X, which… , which in turn samples Work A by Artist A.
Should Artists A-Y all be credited on Work Z?
