I wonder if the biggest issue they have with the music has to do with those on ride videos they try to sell. I mean, that has to get into some copy write issues, selling videos with music on them.
I do enjoy hearing music of my choice on the ride, the ride is OK to me, I do not ride it that often...but I think that is more about things I am not in the mood for....locker, sun in eyes in the AM, I really do not like that lift hill...but it needs the music!
