Saying Mozarts music makes you feel like flying is quite a generalization, Mozart wrote a lot of music and not all of it makes you feel like flying, not even 50%, hell, not even 10%. When I listen too Mozarts Requim I don't feel like flying, I feel like dying.
Sorry about the lay in, you usually write quite intelligent posts. I just have a thing with generalizations and stereotypes, they can lead too misinterpretations. you should say something like this: Blues music was originated by the slaves as a way of relieving emotional tension. Hopefully we have come a long way since that time and the blues form can be used for more then expressing grief.
