I flew on the same international airline for business dozens of times and they always had the same tune on for the first hour during boarding/etc and then again during landing. I've now developed a bad Pavlovian response to that track because it is associated with brutal long-haul travel, jetlag, dry air, customs hassles, etc.

Note: I then got Gold/Platinum ranking, started boarding sooner, and so got exposed to the music even more!

Note 2: International flights have much longer boarding periods and usually large plans, so the time intro music is played is long.
