First of all, the R&R HoF isn't. If it was, less emphasis would be placed of records sold and more on musicianship.
My picks would be Stevie Nicks, the Zombies and John Prine. Nicks has a good chance. The Zombies and Prine don't have a prayer in hell. The rest would never be in my HoF.
Devo, Kraftwerk, Todd and The Cure. Todd more for production than any album in the last few decades but A Wizard, A True Star is a gem. The other three started and kept alive entire genres of music in the US. New Wave, Berlin style electronica (which was already popular in Europe) and whatever the Cure does which is so much more than just Emo.
