They sounds that most affect me, are:
Seagulls - Although at the top of my list, I have never quite figured out why. Perhaps from my earliest days on the Jersey Shore.
Spring Peepers - The soundtrack of my youth.
Four-stroke British café racers - The soundtrack of my 20's
Bob Dylan's harmonica playing - Few things bring me to tears. This, does. Yes - I'm very prepared for the snide comments on this one. lol
What are yours?
Cheers. - Frank
