1. Deep Purple
You can't blame the Rock and Roll Hall of Fame nominating committee for not bringing Deep Purple in. They've put them on the ballot several times over the past few years, but for whatever reason the voters just don't seem to be going for them. It probably has something to do with the fact that the vast, vast majority of voters are American. If the people of Europe had the chance to vote, Deep Purple would have been in years ago. Sadly, many people in America see them as merely the "Smoke on the Water" band. Throughout the rest of the world, Deep Purple are seen on the same level as 1970s giants Led Zeppelin and Black Sabbath. They continue to play huge shows even though guitarist Ritchie Blackmore bolted over 20 years ago. If they ever got into the Hall of Fame, there's a sliver of a chance he'd reunite with them.
