Don't forget hair metal, followed by grunge, both of which dominated youth culture from the mid-80s into the early 90s. Those trends dictated what kids wore, how they styled their hair, the language they used, the attitudes they valued. And, they sold billions of records. I find it amusing that a record like Quiet Riot's "Metal Health" which is where the term "headbangers" came from, began as a defiant , deliberately abrassive, counter culture anthem for rebelious, kids of the mid 80s, but is now a mainstream staple at sports events.
