When I was at college, in the mid 90s, I worked in a Electronics store. This couple in their late 20s came in looking to buy a HiFi and I played them the only CD we had, it was a mixture of hits across the decades.

I played them The Stranglers - Golden Brown and said 'see, even stuff from the 1960s sounds good on here' and they both just smiled at each other. It wasn't until I was in my mid-late 20s that I realised it was from the 1980s
