Perfect Illusion is a pop song. Lettuce not act as if the lead single is the most commercial song on an album, it might have been chosen for a multitude of reasons.
lol video can give a song big push (0.1-0.2) and that push would push it back to top5
That's the illusion right there. Yes the song will get a deserved second boost, but that will only last a day at most. Even radio plays can't maintain it in the top40.
