Pink Floyd was a 1970s rock band of the kind that made music for drug addicts.
That made me laugh.
A coworker years ago described a recording session where the guy on the board putting the mix together was into various recreational drugs. They heard the tape the next day and even the mixer couldn't believe how bad it sounded. My coworker described how fast everything was on the tape as though the drugs slowed down the mixer's mind so much that it sounded normal speed to him.
That would explain the music of Pink Floyd; what sounds like overly extended notes and syrupy flows in extended length songs sounds like normal speed to the zonked out listeners.
