Only sick music makes money today.
I suspect music is auditory cheesecake, an exquisite confection crafted to tickle the sensitive spots of... our mental faculties.
Play the music, not the instrument.
I can't listen to that much Wagner. I start getting the urge to conquer Poland.
I cannot listen to Beethoven or Mahler or Chopin or Bach when I write because those composers require you stop what you are doing and listen.
Wagner's music is better than it sounds.
