Rock probably gets airplay in those countries.
Remember when the UK used to have the coolest music scene in Europe? What happened? When did we get stuck in this endless cycle of MOR/Easy listening/kiddie pop?
Yep, I remember when I first got into metal/hard rock in the late 70's/early 80's groups like AC/DC, Iron Maiden, Rainbow, Judas Priest, Motorhead etc were regulars in the charts and on Top of the Pops and I still have many of their singles and picture discs.
