Saving a song

My experience of listening to "dead" songs after long periods without (nowadays I have gaps of 25 years for some songs) is that the first listen is interesting (from "I thought I had stored every detail but the tone here is something I might not have appreciated on my early 90s stereo" to "I've almost forgotten what happens next") but then the music immediately reverts to its dead state, to be perhaps revived briefly again in the early 2040s and then no more.
