Happily listening to songs from two decades ago with thinking about age - then Ladytron ,Seventeen came on. I remember listening to that at 16. I'm now 33. (There's a couple of other age-reference songs that throw me in the same was as I was either younger or on age - McFly song with the lyrics "she looked incredible, just turned 17" & Placebo's Special Needs).
What are the songs that really make you feel your age?
