Could it be that the Rock Hall Of Fame is finally realizing that inducting acts that have little or nothing to do with Rock has undermined its credibility without adding enough visitors to justify the strategy? We hope so. For the first time in years, the list of inductees isn't peppered with acts that make true fans go WTF?!  The solid ranks of deserving artists includes Deep Purple, Cheap Trick, The Steve Miller Band and Chicago. N.W.A. will also get in during the ceremony on April 8 at the Barclays Center in Brooklyn, but them being included only warrants a w.t.f?
