Sony/ATV/EMI have negotiated a separate deal with Internet streaming service Pandora which will give them an increased royalty compared to the rates paid to members of ASCAP and BMI. Sony/ATV/EMI withdrew certain rights from the performing right societies in the US as they weren't happy with the statutory rates set by the rate court.
Universal Music has now followed Sony's lead and announced that they will withdraw certain online rights from ASCAP and BMI.
