Mystery Quote Revealed

What well known composer said the following quote?

"This music! This music! Take it away! It's here in my head and won't let me sleep!"

It was Pyotr Tchaikovsky. Tchaikovsky was a precocious child, learning to read French and German when he was only six years old. What's more is that he was ultra-sensitive to music, which prompted his parents into enrolling him in piano lessons. At night he would have a hard time falling asleep, because he could not stop the music from playing in his head.
