What do you mean?
I watched the set, they are very good at what they do, anthems ready made for festivals / stadiums. To be in the all time elites I do think they lack a truly brilliant record from start to finish, always tends to be a bit of filler in there imo not saying that it's an easy thing to make a world changing album of course.
Watched Joey Badass' set which was excellent, nice to see a hip hop artist playing with a drummer and keys, it doesn't really seem to match the festival vibe if it's just a dude with a mic and a DJ behind him.
Really enjoyed Warpaint who I hadn't heard of before. Excellent bassist and interesting vocals tones change ups.
Not sure if I can be arsed with Arctic Monkeys tbh.
