Ended on "Deja Vu".
Just listened right the way through again and the album flows PERFECTLY, every track is fucking banging and enjoyable as hell, and the skits / story / concept all work... even where right after "Must be the Ganja" he theoretically passes out after being at the height of his 'drug daze' and journeying through his manic, psychotic, wacky, insane, murderous relapse adventure...
And, "Deja Vu" is him out of that, woken up and reflecting, and so it makes sense for him to be out of character there and would have been perfect to end on...
Because it was supposed to be two albums anyway, so if he had ended there - no "Beautiful", "Crack a Bottle" or "Underground", or closing skit, but just ended on that song with perhaps a little added outro, and then Relapse 2 picks up where that leaves off, with essentially a second relapse, that is ten times more extreme, crazy and threatening... the sequel would have made perfect sense, would have been climactic and, yeah, it would have been perfect to end no.1 there.
If it ends there, it's very very close to a classic to me. Shitty extra tracks ruin it. Tagged right on the end as well, after the rest flows and works SO well. Very annoying.
