If you read my entire post, I said "To me,…" HINT... that means it's my opinion. Beyond that, it's understood by most people who are into music that the meaning of the term "heavy metal" has evolved since it was coined by a Rolling Stone writer to describe the music of Humble Pie or some similar band from that time. Van Halen created a sound and style of playing that, in 1978, was different than what had come before. Everything that I heard in the '80s that was called "heavy metal" or "metal" sounded TO ME like Van Halen. I have no idea what happened in that genre after that.
