why would fair use be at play here? TWC would have paid a license fee through ASCAP or whomever for the rights to broadcast that music. They didn't just download a bunch of mp3 files from Napster and try to disrupt broadcasting.
You're right, of course. I guess I just put a lot of weight on the charm of keeping old things running, and think there's value to the public in allowing free use of music, particularly for non-commercial/educational purposes.
