Incidental music - many rely on this but :-

This is described in the guidance as

"music which is incidental to an activity which is not itself the provision of regulated entertainment, for example music played in lifts or piano music played in the background in a restaurant".

Very narrow "for examples"!

An music at a place of public religious worship "this would excempt not only the singing of hymns or other religious material at a religious service, but also the performance of a classical concert at a church" says the guidance....what of a church brass band concert etc? May be ok but the guidance does not add much.
