What royalties does SoundExchange administer?
SoundExchange collects and distributes royalties from statutory licenses, including:
Digital cable and satellite television services (Music Choice and Muzak)
Noninteractive "webcasters" (including original programmers and retransmissions of FCC-licensed radio stations by aggregators)
Satellite radio services (XM and SIRIUS)
I don't think we fall under this group, but it looks like the radio on your cable service will now be a pay service.
