Dick, I agree that there is only a finite amount of time and places, and that "commercial" music has crowded "non-commercial" music off the stage.   However, the term "commercial" should not be viewed as a word that demeans the artistic merit of the song. Commercial usually means that it sells well and is popular.   "Noncommercial" usually means that it doesn't sell well and reaches a selective audience. Both can have either good or bad merits.

It also means that we have choices to make. We should spend time listening to the music that moves us as individuals.
