In car, I give chance to the radio otherwise I barely listen to it. So.. when,unexpectedly, nice old song starts I let it throw me back in the past, or as you say back to some places, remembering certain people. Depending on the mood, landscapes or weather different emotions can overflow. For an example, song Wake me up by Avicii reminds me of time spent in Greece, Radioactive by Imagine Dragons reminds me of Austria. These songs aren't in my playlists but I love to hear, usually randomly on the radio.
