It is known The Weeknd is VERY demanding about everything. In 2016 he was one of the two headliners for Formula 1 in Austin, but he was the Sunday post-race headliner (afternoon slot), while Taylor Swift was the Saturday night headliner. Rumor says Weeknd didn't want to play while the sun would be out (4-5 pm) so he backed out and the organizers had Usher & The Roots replace him. In 2017 he was meant to headline Lollapalooza, but his name was not the first one on the poster. He backed out last minute right before lineup drop. They brought him back for 2018 and of course his name was the first one on the poster (ahead of Bruno Mars). He is pulling the exact same bs right now with Coachella with asking for the same $$$ that they were paying Kanye West before he dropped out, Coachella was going to pay Weeknd less cause he is not as big as Ye, but I guess Coachella is desperate with the event starting next Friday that they just decided to pay him.
If The Weeknd house is not the first one announced I will be incredibly surprised. I'd expect his house to have a "headliner" placement on all general posters and promo as well.
