Rarely will you find Floyd dishing up catchy hooks, tunes short enough for air-play, or predictable three-chord blues progressions; and never will you find them spending much time on the usual pop album of romance, partying, or self-hype. Their sonic universe is expansive, intense, and challenging ... Where most other bands neatly fit the songs to the music, the two forming a sort of autonomous and seamless whole complete with memorable hooks, Pink Floyd tends to set lyrics within a broader soundscape that often seems to have a life of its own ... Pink Floyd employs extended, stand-alone instrumentals which are never mere vehicles for showing off virtuoso but are planned and integral parts of the performance.
