Yeah, I would hardly call it a recap. Sure, it's many musical pieces stitched together in a linear way, but it is certainly greater than the sum of its parts and makes a coherent composition. It isn't simply one piece fading into another; there has clearly been a lot of effort to edit the music to make the pieces flow into each other as a single narrative.
As for its legality regarding the sampling, I would be inclined to allow it. There is precedent of similar entries in NSC, and each of the samples makes up a very small fraction of the overall piece (roughly 1%).
However, I admit that this is partly due to the sheer length of the piece, and if you add up all the samples that appear in previous entries (13 if I'm interpreting Jochen's post correctly), that makes up 13% of the whole entry, which is more significant. So I could also see an argument for disallowing it, although I am sure there have been entries in the past that have surpassed 13% in samples.
Overall, I think it would be good to get some more opinions.
