You could get cash back for music you’ve already bought. It’s not a store rebate. Several states filed an antitrust suit claiming music companies and three big retailers conspired to limit how cheaply they’d discount popular music CDs. The suit claimed they acted illegally to stop other stores from offering music at discounted prices. The settlement announced today will let anyone who’d bought recorded music from 1995 through 2000 file a claim for payment up to 20 dollars.
