It's simple, really, if we split the work up, we each take a few songs, change a word or note, here or there and they are no longer the copyrighted material in contention that we don't even know the name of right? Then Dick and Max or whomever can copyright THOSE versions and do whatever they want with them. When we registered my brother's work wiht the copyright office, thatw as what we were told. Anybody could change them ever so slightly and our copyright would not cover it. Has this changed?
