The battle over Prince’s estate is winding down.  Three of Prince’s six siblings have sold nearly all of their share in the artist’s estate to music giant Primary Wave.  That puts the company in control of nearly half of Prince’s total estate.  The three remaining siblings have held on to their shares, and are finalizing tax issues to close out the disputed estate.  The singer died more than five years ago of a fentanyl overdose and didn’t have a will.
