TK, I guess it's all subjective, but I guess I delineate it the same way SiriusXM does. Maybe because I've been a subscriber for seven years! But they have the 80's station which plays it all. Hair Nation which plays the hair band rock sound. Then there's Classic Rewind, which is mostly 80's rock. Artists I'm thinking of are Don Henley (of course!), Tom Petty, Aerosmith, Cars, Police, Journey, Genesis, Mellencamp, AC/CD, Pat Benetar, Boston, Van Halen, Bob Seger, Springsteen, Cheap Trick, you get the idea.

The Hair Rock bands, to me, are more like Bon Jovi, Ratt, Def Leppard, Guns N' Roses, Europe, etc.
