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)
