The linked document explains this, but it's because there is no federal copyright law for pre-1972 sound recordings. Before 1972 there was no federal copyright law for sound recordings, and then congress did not want to change the state-law copyright status of recordings made before the federal law was passed, so it was intentionally left non-preempted so that state law applies.
