I'm sure you'd feel the just as magnanimous if it was your material being plagiarised, whether it took you 2 minutes or several years ?
No point in having any new ideas or thoughts at all on that basis.
I see in the press at weekend that McCartney and Elton John are kicking off about copyright. Their copyright in particular.
Mainly because they think, correctly I guess, that AI will use their output to create new music. But I cannot see that they can stop this from happening. Just as they cannot stop a person from doing the exact same thing after hearing their work. Not only that, The Beatles, Elton, Beach Boys and many others copied Buddy Holly, Don & Phil Everly , Roy Orbison, Bo Diddley etc. Musicians like Chuck Berry, Rolling Stones etc have made a living adapting stuff off artists from way back? Not much is totally original, or uninfluenced by earlier work. From the 1950s and for twenty years there was an explosion of variations from earlier work. Just about everything is adapted from something earlier anyway. We haven't heard anything really original for maybe 50 years. Maybe AI will change that?
Apart from that, most of the stuff Elton and the Beatles wrote was done in a few minutes. So not really a bad return for their time and nothing to complain about.
We recently had a similar conversation about publicly posting copyrighted written material.
The answer here is the same. Whether a song writer earned $10,000,000 for a song or $10 for a song is irrelevant. What matters is the principle of
Intellectual Property rights. The person created the IP. That IP, whether it's a book or a song, belongs to that person.
There are a lot of theories about how that right can and should be enforced, and under what circumstances, but the principle is well understood.
The problem with copyrighted music is more subtle in some ways, but not entirely different. If McCartney or Elton John or Willie Nelson created a composition, it's theirs. Whether it was in turn inspired in whole or in part by Muddy Waters, John Lee Hooker, Lead Belly, Doctor John, or one of the hundreds of semi-anonymous musicians of the 30s, 40s and 50s is not definitive. And that's only referencing American singers and song writers that I know about.
Riffs and motifs and even lyrics are not universally unique, although in some combination they become more so. I think it's more of a question of how much of that influence was retained in the final product.
Famous musicians have no more "right" to control their music than musicians currently living in a one bedroom apartment in Soho and trying to make a name--and a living--for themselves writing their own unique songs. But they also have no less right to do so, just because they already became rich and famous.
AI exacerbates the problem of infringement by making it easier to plagiarize. We're in for a rocky road trying to figure all this out.
