The early Seventies were great. Tons of variety were seeping into the listening habits of young rock n' rollers. (Into the charts, maybe not so much.)
We heard, all of a sudden, African music (Highlife, Afro Beat, South African), Japanese music (Pink Lady even had an American TV show; don't forget the Sadistic Mika Band), Italian pop music, Brazilian. I know that I heard it, and if I heard it, it could be heard.
Of course now we can access every damn thing on the YouTube, but forgive this old man for wondering if a little bit of variety would be a good thing in the listening of everyday people too.
