Im not saying its better.
the grass is always greener.......for weekend 1.
As others have said, some of the set lists changed a litte.
One thing I noticed about Weekend 2, and I don't know about Weekend 1, is that all of the set started pretty much on time Weekend 2. I remember EVERYTHING being like 15-20 minutes behind in 2011, but 2012 things started on time. Was kind of nice.
However, one set that didn't start on time Weekend 2 was Dragonette's set. It was the hottest part of the day on Saturday (jsut a little above 106F) and she literally had to go through 3 computers because they kept melting/dying. Otherwise, things were on time.
