I don't think Pink Floyd is overrated. Dark side of the moon maybe. But when you've made albums like the Piper at the Gates of Dawn, Meddle, Wish you were here and Animals, you deserve all the credit you get. Besides, DSOTM is a good record as well. It is a shame though. There are much more exciting groups from that era, that are a lot less heard than Floyd. You always here people about Dark side of the moon. But you hardly hear people about Tago Mago or Ege Bamyasi.
