Er 🤔 still non the wiser, only observation was MB on the quick skip through i did, seemed! to be playing music with the same tempo/style all the way through. In other terms not alot of variation. Maybe I just don't need to know. Obviously I don't have a scooby what I'm talking about. Thanks though, for trying to educate me.
