I never really liked that album or at least the songs all that much, until listening to it start to finish. Yeah it's a concept album and it's a cohesive album where one song leads into the next.For me it is a concept album, especially since when you remove and listen to one song, like Money, it just doesn't sound right by itself. Music fans have grown used to the way it sounds by now, but as a stand alone song back when Pink Floyd was in its peak of fame it's just weird,
The concept that binds the set of songs are the anxieties of everyday life, IMO.
