I was born in '87 so I missed out the bulk of the '80s music that is now most thought of when someone says 'eighties'. People think Duran Duran, Spandau Ballet etc.
90s music that I grew up with I only liked for the nostalgia and memories they bring back, not as music, and I think music in the charts has been on a downward slope since 2000.
But in recent years my niche is funk and soul from the 80s and some that spilled over into the early 90s like New Jack Swing; Alexander O'Neal, Kool and the Gang, EW&F (okay they were 70s also) and even obscurer artists like Johnny Gill, Guy, Mint Condition... Some songs of this genre was bigger elsewhere, where most of it came from, but some were sizeable hits in the UK. For instance that group 'The Limit' from Holland IMO was one of the best and had many great songs but only 'Say Yeah' made it to the UK chart.
Interestingly in France recently, there has apparently been a resurgence of 80s-style funk.
Would some of this be liked today? A majority of the UK chart is r'n'b, but not the good kind. Not so many guitar bands it seems.
