Seems Universal is tightening the screws on everyone.....
"Prime Music's track listing includes songs from Justin Timberlake and Bruce Springsteen -- but it doesn't include artists like Jay-Z and Lady Gaga.
That's because Amazon reached signed deals with Sony Music and Warner Music Group, as well as many of the top independent labels, but it couldn't reach an agreement with No. 1 Universal Music Group (
reportedly because of a disagreement over fees)."
