Short take: get this version of PDK. It's identical to the original vinyl issue and fixes the problems on the earlier PKD/Simulacra mp3s (which must have been based on some faulty master tapes?). Crawl is an example: it's the correct speed here, and has the guitar part (missing from the PKD/Simulacra issue) around 2:00. Hate to be a weirdo, but I listened to this album so much growing up that its burned into my brain: the PKD/Simulacra reissue is just not right! And my vinyl is worn out.
