He owns to the rights to further use of the songs. They still get money for the albums with their voices on there. Those're still their intellectual properties.

For example, when The Royal Tenenbaums used Beatles covers, it was Jackson who got the money and who allowed the use in general. If they used the original tracks with the voices of John, Paul, George and/or Ringo, the surviving Beatles and the families would be getting it, though I believe with a cut to Jackson.
