I was in hospital aged eight and the hospital radio kept playing two songs that were around at the time, 'Mated' by Jackie Graham and David Grant, and 'A Certain Smile' by Midge Ure. Heard both these songs again for the first time in ages within the last 12 months and was instantly taken back to a hospital bed
I reckon the songs that do this best are the ones that weren't such big hits. Huge hits such as 'Like A Prayer' for instance no longer belong to the era in which they were released, cause if u listen to enough radio, you will have heard it once a week for the last 15 years! But the Midge Ure song, for instance, has hardly been heard by anyone since November 1985, so when I heard it a few months ago, it seemed dislocated and still to 'belong' to that specific time.
Recently had an experience with 'Never Be Lonely' by The Feeling. It was playing in the pub and a girl with whom I have fallen totally in (so far unspoken) love was singing along, oblivious to me for a second just gazing in total adoration. And I know if I hear that song in ten, twenty years time, I will instantly be taken to that moment, and her, and how I felt so totally in love. Whether or not anything ever happens between us, I'll always remember that song and that moment. If we ever marry, I'll tell her and say I want it as our first dance
