Psychologist dissects Pink Floyd's 'Dark Side of the Moon'

Waters writes dark, disturbed, and anguishing lyrics. The sorrowful lyrics are masked by the spirit lifting music produced by Gilmore and Wright. 

“Well, Nick never pretended. But Gilmour and Rick [Wright, the keyboardist]? They can’t write songs, they’ve nothing to say. They are not artists!” said Waters. “They have no ideas, not a single one between them. They never have had, and that drives them crazy.”

The man has no respect for his co-workers or their contributions. It's a wonder that PF lasted as long as it did.
