Satellite radio broadcaster SiriusXM has filed a federal antitrust complaint against clearinghouse SoundExchange and the American Association for Independent Music (A2IM), claiming the bodies conspired to give SoundExchange a monopoly in the distribution of music licences.

Sirius XM has reached a settlement agreement with a class of former subscribers, ending claims that the company’s merger has created a monopoly in the satellite radio market and led to higher prices for listeners.
