The Rock and Roll Hall of Fame just announced its induction class of 2014, and some worthy additions will be joining the hallowed hall next year, including KissLinda RonstadtPeter GabrielNirvanaHall & Oates and Cat Stevens. But a handful of classic-rock favorites who were up for nomination were once again snubbed by the Rock Hall.

Pro-rock kings Yes, whose long career includes seven Top 10 albums, helped define a genre during a decade when new musical paths were traveled every other month.

Fan favorite Deep Purple scored their first hit album in the late '60s and peaked in 1972 with 'Machine Head,' which included the classic 'Smoke on the Water.'

While the Zombies had a string of hit singles in the '60s, their greatest triumph came in 1968, after they had broken up, with the great 'Odessey and Oracle' album.

So which of these three legendary rock bands do you think was most deserving of a spot in the Rock and Roll Hall of Fame this year?
