I visited Washington DC on a band trip in high school about 15 years ago. Right before I left, I bought Five For Fighting's CD: The Battle For Everything. I listened to it the entire time I was there (as I only had a CD player). Anytime we were on the bus, I was basically listening to that CD.

Now, If I ever hear any of the tracks from that album, I have a flood of memories that come back, and I think that is the reason why I remember that trip so well.
