mtv was the most effective tool to date for capitalizing upon and reinforcing the concept that pop music was about fashion and trendiness and not about music.
So.... painters from the Romantic period weren't about fashion? Sculptures from the Art Nouveau period were not about fashion? Composers from the Classical Period didn't hang out in palaces and attend the trendiest parties?
Man, ART, in every form, has always been about trends and fashion. 80s pop music was just another form of art like any other.
You can no more separate music from fashion than you can movies, paintings, sculptures, photography, etc.
Why, even the anti-trendy grunge movement was (dare I say it) a TREND. Many grunge fans bemoaned "selling out" and trying the like everybody else..... all while dutifully wearing their flannel shirts like a good little grungy should....and just like all the other grungies were doing. There was no more individualism in grunge than there was with Valley Girls or punks or any other group following a trend. The flannel shirt was a fashion statement. Not wearing makeup on stage and looking like you hadn't had a shower in weeks WAS THE FASHION of the day.
. They went downhill real quick after that.
I don't know what they show now as I stopped paying outrageous cable fees over 10 years ago and went to free over the air broadcast TV.
As a city dweller, it was about everywhere in the beginning.
