ISBN for album covers? But unfortunately imho album covers have no market value in today’s music world as “a song “ is released on YouTube gets consumed quickly and you are left out with seeing some random cover of the singer on iTunes but it could well be a good ideas to have album cover credits aggregated to a single platform especially from 70s , 80s and 90s although I doubt the revenue model of selling hq album covers as 4 big record labels will shield this from being executed by the same token there were start up ideas tossed around selling chords and lyrics as a valuable byproduct besides the hefty charges of streaming license deals but …….afterall music industry is for monkeys to build a business and timing is not good.
