and Gianmario Scotti - yeah, I'm blessed/cursed with neverending
  music in my head since I was a kid. Perfect pitch, everything
  makes music. It's raining right now... it's making music. Fan to
  the motor next to me is making music. I can call out their
  pitches if I want. TOtally useless ability but it never gets
  dull. The frustrating thing is, my brain puts together songs
  I'll never be able to play or get 'out", so i just have to enjoy
  it. I suspect a lot of people have that issue, so I'm just
  happen that I do it at all.
