Sometimes I feel as if I am a bit unique on various music forums I post on, because I have almost zero nostalgic feelings connected to music.
Once I reached about the age of 20, music stopped being the "soundtrack to my life", and became something to appreciate on a purely artistic level. Once that happened, the idea of listening to a song because it reminded me of a great time I had during my youth, became trivial to me.
Not that I don't listen to some music from before that time, but it still has to meet the criteria* I love in music. I do not listen to it because it came from a certain time in my life.
*Those criteria being: very high levels of musicianship, deep and broad range of emotional and/or intellectual content conveyed, moderate to high levels of complexity.
