I don't think there's any merit to the sentiment that songs are being repeated too much. Yes, no one enjoys seeing songs played two nights in a row, but it's always been like that. Always. Nothing new. Didn't I read somewhere that Phish has played more unique songs this year than any other year but one? And likely with the remainder of this run and NYE should set the record.

The Light -> Slave -> Tweezer was great. Light went everywhere.
