IMO, there is very high chance that someday, some record label will create "new" songs or remaster existing songs for bands that are unable to perform themselves anymore, be it due to illness, age or death, using some kind of artifical (ML) voice generation. It would probably never be sold to the public like Cryptons products, though, to protect the brand. And then we have come full circle. Imagine four ABBA Vocaloid, milking out one song after the other for Universal, for the rest of our lives. It would be kinda funny, IMO. :D
