def corrected
  # you want to provide this with the smallest set of possibilities
  # for performance reasons. Left and right bounds limit the values
  # where the comma error could be

  # For instance, with the following headers:
  # [playid,playtype,genre,timestamp,artist,title,albumtitle,label,prepost,programtype,iswebcast,isrequest]
  # the only values that could contain an extra comma are "artist,title,albumtitle,label"
  # therefore our left_bounds = 4, right_bounds = -5
