I was never a fan of all the different names that music gets given. Especially when arguments occur as to which genre a band belongs to. It's music. Do you like it? Yes? Well that's fine. I can listen to pretty much any kind of music but my heart is always with hard rock. Any music with big guitars gets my attention so if they are considered metal or hair metal or glam metal I don't care. I love old hard rock, I love new metal.
In the 80's all that was about for heavy metal fans was Iron Maiden, Def Leppard, Motley Crue, etc. etc. That is what we called Heavy Metal. It was during the 80's that other more extreme bands started to develop and the Grunge movement spawned from this.
