This crossword puzzle auto-fill program coincidentally got ¾ of the way to a mini-theme by randomly picking phrases out of a hat…

  M   S
  I   O
INSIDEUSA
  T   R
  U   N
  N   O
ERIKSATIE
  N   E
  G   S

If only that INSIDE USA were instead MUSIC CUES or somesuch, it would be time to buy a lottery ticket or watch out for asteroids or something.

Wow, MISTUNING and SOUR NOTES is pretty sweet.
