Let me warn you upfront; you will not like all the songs on this album, no matter how die-hard a fan you may be. It is a plethora of musical curve balls, that is unsettling, confusing, amusing, and addicting. It may also be one of their most important albums, in the sense that they try so many different things instead of sticking to a safe, poppy formula, it set a precedent for them to continue to experiment in their later works. I like the fact that one gets the sense that they do not care what you think of the contents of the album; you get what they give you, and they continuously play with your mind throughout. The record scratch at the end is no less alarming when one listen's to it on CD. You will hear something that you did not before every time you listen to it, and you may never forget 'All Day Long'.
