Good call, great selection, Kathy.
My teenage musical education began in the early 80s, by which time the previous decade and its sounds were already being discarded as woefully uncool and cheesy.
This meant I had to wait until later in life before having a chance to (re)discover a lot of that fantastic music, especially disco-adjacent stuff, with an open mind.
I was actually commenting just the other day on another article about only coming across Billy Joel's fantastic Piano Man decades later, having dismissed his 1980s Innocent Man incarnation in the same cheesy box as Christopher Cross and Barry Manilow (the latter's work also being worthy of reconsideration, despite all the stick he got in the 80s).
Aside from Piano Man, which would definitely now be on my list, here are a few others I would add:
The Pretenders – Brass in Pocket
Sister Sledge – Lost In Music
Blondie – One Way Or Another
Chic – Le Freak
Iggy Pop – Lust For Life
