There's a new battleground in the fight over the Performance Rights Act: The FCC.

Following its filing of a complaint over broadcasters' tactics, the MusicFIRST coalition, which represents artists' orgs and record labels, noted in a release on Monday that the FCC is taking public comment on "whether and to what extent broadcasters are engaging in a media campaign, coordinated by NAB (National Association of Broadcasters), which disseminates falsities about the PRA (Performance Rights Act)."

The legislation would require that broadcast stations pay performers when their songs are played over the airwaves.

MusicFIRST claims that radio stations have refused to air their ads, and that artists who support the act have had threats that their music will be pulled from playlists.

NAB spokesman Dennis Wharton responded: "NAB will be commenting on the distortions raised in the musicFIRST petition at the appropriate time. Contrary to the suggestions in the petition, broadcasters are under no obligation to carry everything that is offered or suggested to them."
