you don't like unaccompanied singing - you have said on numerous occasions that it bores you

Not true, Jim. I sing unaccompanied myself. I like some unaccompanied singing just as I dislike some accompanied folk songs. What I have said is that I dislike is having to work at enjoying music. Life is full of songs I can enjoy without effort and is too short to waste time making myself listen to something I don't 'get' first time round. If that makes me shallow, so be it.
