It's more ride than Queue. Only because the ride starts exactly there. The problem with most rides is that the Queue isnt in a building like Space Mountain or Dinosaur. They are outdoors. So for rides like Big Thunder, the music you hear is also the music for Frontierland and visa versa for other attractions across WDW. Regardless for the actual terms, WDW has some of the most memorable theme music of any Theme Park Operator in the World.But it isn't really music in the queue of HM. TOT starts almost as soon as you start walking through the walkways.
The question is, should the library room with Rod Serling be included as part of the ride or queue? I would include it as part of the ride.
