You ain't listening to the right 80's music. I love the funk and soul of the 70's but OVERALL... I would take 80's music over the 60's and the 70's music. 80's music has more variety of Funk, Soul, Pop, Rock and Rap.
Ever since the 80's ended... music groups and producers have been trying to recapture that 80's sound... even still today(2017).
Let's just say that If I was on a road trip and had to listen to nothing but music from the 60's, 70's or 80's... for 10 hours straight.... the 80's would easily win.
