Just joined Taxi an hour ago!

I have a question regarding the broadcast networks not licensed by ASCAP. I recently signed an exclusive music deal with a new tv show coming to Ion. We're doing 167 tracks for one season and 225 for the second. Super excited about the potential here!
My question - Are we subject to local tv royalty rates because they're not directly licensed by BMI/ASCAP? If so, how exactly does that work? I know Ion is a pretty nice sized network with 200+ local affiliates and 60 O&O stations, but is their potential to land a few nice royalty checks?
