No time for music

There's been little time for music recently, except of course in my head. I wonder if any other musicians, or non-musicians have this constantly running soundtrack going in your head. It usually arises from something that I had been listening to, but I have to admit that there is rarely a time when some sound or another is going through my brain (I'm glad something is at least). And it's rarely just a tune, but usually a full blown composition.

Now what I need to do is expand my repertoire. My head usually plays Verdi or Beethoven (Egmont or Eroica usually). I'd really like to hear a little Bartok in there once in a while or Schubert. I rarely hear opera though, odd since that is my overwhelming passion. Perhaps the high notes are just too much for it.
