The best line up but the worse schedule

So there is this electronic music festival I want to go to. It's a Halloween party that's going on the 30th and 31st of October. I can only go one day but can't decide which day to go.

The party on the 30th has a sweet lineup! Some of the best DJ's will be spinning. I love pretty much all of the DJ's spinning on the 30th. The 31st only has a couple DJ's I like. The rest of the lineup up the 31st kinda sucks. But one of the few DJ's I like happens to be one of my top favorite DJ's of all time. I've seen this DJ duo before though (Crookers) and they were awesome. But most of the DJ's at this festival I've seen anyway.

So, which party do I attend?

 

You say fuck it and go to both.
