If you went looking in the metal section of a record store in the 80’s there were a ton of bands that are not considered metal today. Bon Jovi for example were absolutely considered metal, Guns N’ Roses were metal, Def Leppard, Whitesnake etc. Even Queen were borderline metal. If you read metal magazines in that time like Kerrang and Metal Hammer, these bands were never off the cover. They were headlining metal festivals like Monsters Of Rock (the precursor to Download).
I remember when Bon Jovi released Keep The Faith as the lead single off that album and arguing with my mates as to whether they were no longer metal.
Times move on and those bands would no longer be classed as Heavy Metal, more heavy rock, hard rock etc. Queensryche absolutely dipped their toes into that with the likes of Jet City Woman, Another Rainy Night Without You but other songs like Surgical Strike, The Needle Lies are still very much traditional Heavy Metal to me. Yes it’s not Slipknot or Slayer but it’s still metal in the same way that Iron Maiden are still metal.
