Val, I really believe that you got my point. I don't get the law thing, so I leave it all together out of this discussion. I don't even like to drop the ethics bomb. But it just reminds me of the Monty Python sketch were Palin claims authorship of every Shakespeare work. Well it sounded ridiculous and very funny, but in view of these "new" songs I wonder.
I was only saying that huge artists that want to use something, have to mention the original source, if not for money, for a graceful "hats-off". We are bound by copyright, not freed. Just consider this unlike story: Dylan throwing a lawsuit to our man for stealing his music.
He has every right since the song has only him as author.
I know that all these have been mentioned before by writers from big magazines and newspapers that can influence the public, and still nothing happened, so who am I to mention such things here.
But for those interested :
