Also "Perfect Day", some might say is a lullaby to drugs.
(Can't believe some comments are just sooooooo tone deaf thanking I'm expressing dislike for these amazing artists rather than criticising the industry that feeds on them).
Because it's an over-dramatization. Lou wrote those songs and put them out for commercial sale. No one made him. They aren't being doubly exploited in his death.
This is part of the tension that lead to Lou kicking John Cale out (experimental rhythms and screeching viola were never going to take them to the heights of rock and roll stardom) and eventual breakup of the band.
If anything, I could see Bowie and Warhol dragging Lou into the smoky, off-color limelight of the underground and alternative arts scene, away from the pop stardom he was fixated on. He certainly left Warhol behind abruptly and unceremoniously when he felt he was being pinned down. Immediately after was when the Underground produced their most poppy, mass appeal songs like Rock and Roll, Sweet Jane, Who Loves the Sun, and Oh! Sweet Nothin' (some of my personal favorites).
