For me it isn't just music. If I really need to think through a project with creativity, I put in my Amedeus tape. Mozart. Or Immortal Beloved. Beethoven. Or if a n old musical is playing on TV, that is running. Yesterday was "The Singing Nun". Music yes, but with a story for me. Or I play Fiddler on the roof. The King and I with Brenner and Kerr.
Ok you get the picture. and I do some modern ones like, "Mrs. Doubtfire".
I can do marathons of NCIS, or Burn Notice.
