Mozart is fun to listen to, with his tinkling little melodies. He can be repetitious, though, playing the same tinkling little melodies over and over.
What I really like in the classical realm are Strauss waltzes. Viennese waltzes. I can actually dance to those. They get inside of my body and move it for me.
I have a favorite quiet music station I like to listen to in our satellite programming. It really is calming.
