On the same note, in his book 31 Songs, Nick Hornby argues that the songs that are truly the greatest of your life do not bring back one particular memory. Because if a song has really become part of you then you have listened to it so often that it is not tied to one specific event.
This seems to make sense, but then the very first song from Recovering the Satellites that I heard was Angels of the Silences, and I remember, when it began playing, a 14 year old Chris and a 14 year old Helen jumping around the bedroom of her house in Penarth.
