The 3 sections mentioned are entirely preferred. Only Love Bug and Mighty Ducks are not. We stayed in Mighty Ducks in Nov 2012, and it was closer to ASMusic's buses than ASMovies bus stops. Returning home from the parks, sometimes we took the Music bus, sometimes the Movies bus, depending on the waiting line. Music's gift shop and food court were about equal distance as Movies'. So sometimes we'd stop over to ASMusic for a meal/shopping. We felt we got the closeness of a preferred room without paying the premium, because of our nearness to ASMusic. The map you might be recalling with partial-building preferred rooms is Pop Century. I've seen that map, too.
