Thought of another aspect
The 80s/Mtv was a global phenomenon
Until then American music (and English music that sounded American) was exported
But MTV allowed for a lot of importing as well
As well as British acts who actually sounded British - The Cladh to Madness to The Pogues to Dexys Midnight Runners
Also reggae sounds creeping in with Musical Youth and Eddy Grant (I’d put Marley in the ‘too big’ category)
You know that Nina Hagen grew up in former East Germany and that her father, Wolf Biermann, was seen and revered as kind of a East German musical Che Guevera in the 1960's and 70's until he became an outspoken dissident of how ruthless, repressive, cruel and harsh GDR were towards outspoken artists, musicians who didnt completely tow the Stasi's and GDR leadership official party line about "socialist realism". Wolf Beirmann actually was expelled from the GDR IIRC, in 1975-76 when he performed for trade union workers at a West Berlin automobile plant.
Even today, most Germans see Beirmann as sort of their Bob Dylan.
The 1980's were a wonderful time for music, even what we term today, " overly-commercial" music because often it was entertaining, enjoyable, fun and worth listening too. Even some of the underground acts that would become famous "alternative" bands in the 1990's like R.E.M. when Michael Stipe actually had long hair.
