My vote goes to POB. I think its my favorite album ever, really.
I understand about the "party music" appeal, but that doesn't really constitute a great album, does it? I hope not. I think its just the quality of the material on the album, and the extent to which that quality affects you. All these kinds of things are purely subjective, yet fun- at times. But I kind of enjoy music that really shakes me up and makes me think and sort of "disturbs" me the most. In fact, the White Album is my fave Beatles album because I got this reaction from it the first time I heard it.
But, you know, different strokes for different folks.
