Robbie knows so much about the forms he uses that the songs are able to be technically superior to all that trash on the radio. Symphony No 1 in Eb, which conveniently is the first track of the album, is a good example of how deliberate choices comprise the album. If you listen to the sensual Book Club, you will be two tracks in to the entire album and not want to stop until you're done with the entire thing in one sitting! (Malort is another fave)
