I love using #mythTV to grab TV schedules right from the broadcast signals themselves-- no need for online access, and having stuff recorded with automatic commercial removal.
What about radio listeners? There are great periodic programs like #MusicalStarstreams (which I think is broadcast in Hawaii but gets mirrored around the world).
Sadly, I looked into the digital info that’s embedded in audio broadcasts, and unfortunately it only contains the track playing right now; no scheduling info. In principle that’s not a total show-stopper. We should be able to get scheduling info online. But so far I have found nothing. The closest thing is this:

That’s great for finding stations that play genres you like, but it does not have program-specific scheduling info. No way to search for “musical starstreams” and get back a list of times & places where it is broadcast.
