I guess that most people would look back at their teen years and early 20s as the 'peak' decade(s). That for me was mid 80s to mid 90s, so all the stuff that got me into indie music in general, eg The Housemartins, The Smiths, New Order, Stone Roses, Happy Mondays, Pulp etc, plus some good mainstream music like early Madonna, Prince, Michael Jackson. Back then was very different in how we consume music, so I'd suggest we valued music much more than our kids do. Buying music meant saving up to buy vinyl or cassettes, actually going to the shop to buy them, then playing the bejaysus out of them when you got them home. Taping from the charts on a Sunday evening and trying to cut the DJ out. There's still some great music being made now, but it's a lot more dispoable with the likes of iTunes and Spotify.
Anyway, time for another Werther's Original!
