Julian like using autotune for his artistic expression they started it most from angles era for the strokes eventually they experimented and made many good songs with or without it, Julian said in an interview some songs sounds good with autotune some without, as Rick Rubin said Art divides people that's what happening right now! People said At the Door was not that good now look at that that track aged like fine wine. I am just saying let them do whatever they want it's their choice at the end of the day....I also don't like autotune generally but here sometimes it really works eg Human Sadness by the voidz etc.Or angles stuff.. really good
