Fantastic point about listening to one song over and over again. I have typically purchased an album before a trip, and then listened to that throughout the trip, so any song on that album can hopefully bring me back to that trip mentally.

I unintentionally tried your approach on a recent trip to Iceland, and the same song kept coming on. Over a year later, that one song reminds me of so many parts of the entire trip. I'm going to pick just one song per trip from now on - thanks for pointing out that this approach works!
