Even as a Justice fan myself, I feel the same way. It sounded off the first time I heard it in person at Coachella. I was kinda thrown off maybe because Im so used to hearing it without a pitch in vocals. This version would have been better imo.
Always thought that looping the first two lines of the song during the 2min drop would be exquisite. That and maybe a more appropiate transition to the silence where "We are Your Friends" "would be, are what this lacks to be just as tasty as the album version. I was never bothered by The Party in this but that do is just personal preference
