This will be a spirited discussion, but I agree with what everyone is about to say. The Rock Hall of Fame is now diluted and meaningless. Its not a bad thing, it just means that the heyday of rock is not currently the top of pop music like it was from the 60s through the 90s.
I keep my own personal rock hall of fame tucked away inside my head. I limit it to 10 bands:
Elvis
Beatles
Rolling Stones
Led Zeppelin
Van Halen
AC/DC
Guns 'n Roses
Eagles
Queen
Tom Petty and the Heartbreakers
Its nice that Run DMC, NWA, Tupac, Janet Jackson, Jay-Z, and Dolly Parton get to hang with my personal picks in the real RRHOF, but Rock and Roll they are not.
