I would put them into the Hall in this order:
Maiden
Journey
Priest
Crue
Styx
Leppard
I put Leppard at the bottom of the list for selling out after Pyro. That band should be punished for going from playing great rock and roll to playing pop songs. High and Dry was so, so good. No to Ratt, Whitesnake, and many other hair metal bands. And, this is coming from someone that listens to hair metal almost daily. It was fun music and some of it was good music but it is not Hall worthy.
I would love to see Motorhead, Slayer, and Megadeth in the Hall but don't see it.
