For hundreds of years people have talked about artists having inspiration, but often, some persons would say, write us a symphony or write us a song, on commission. The artists would come up with a masterpiece without waiting to have their muse inspire them.
My mother always told me, even if a song has been done a thousand times, you can still bring something of your own to it. I'd like to think I did that.
Facetiousness is allowable when it is the most proper instrument of exposing things apparently base and vile to due contempt.
