For me there is a difference between loud music at home, I like opera at a fairly high volume, if I am home alone. But when I go into a public space, I dislike very loud music. Most of
the folk sessions I attend take place in fairly small venues, legion halls and pubs. If I walk in and see that half the room is taken up with "equipment", I just turn round and walk out.
I also leave restaurants where the "background" music is so loud that you cannot have a conversation.
