I had a problem with disk crashes and general computer mayhem a while back. A bunch of my tags got screwed up, and now I want to fix them. The artist and year fields have been particularly affected. They read Bob Marley/Bob Marley/Bob Marley (anywhere from 2-4 repeats) or 1992\\1992. Sometimes there is a blank character box, too.
Is there an expression that will delete the slashes and repeated values?
