I'd imagine DMX didn't have a will. And given the fact that he had to re-record his music, he must not have been getting much of anything from those album sales beyond the typical royalties.
Prince not having a will still blows my mind. The only way I can understand it is that...maybe as such a devout religious person he simply didn't care about what happened to earthly possessions after death. It's the only thing that makes sense.
I think they were just postponing it, they were probably gonna do it when they got older. Anyway R.I.P. DMX and Prince.
