On the exterior, RPC-635 appears to be a normal box of non-anomalous 12-inch LP vinyl records

Something doesn't quite add up here…
If a sapient entity is to listen to RPC-635, numerous anomalies may occur, each coinciding with a different song. If one is to listen to the song titled "The Color out of Space," for instance, the listener's vision will become a swirling mass of colors.
Clinical writing protip: Examples are for cowards. I appreciate it when an author has the courtesy to write a clear explanation, but wake me up when there's something that you need an example to explain.
It has been hypothesized that, if the album were to be played at a party, all attending members that hear RPC-635 in full will be either mortally wounded, or instantly terminated by the anomalies contained within the record.
This line just seems weird and pointless. RPC-034 doesn't need to explain that it would cause serious injury to the average person. Yes, it does tell you that someone was injured by it, but it doesn't come out and say "as RPC-034 can burn through human skin, it is extremely dangerous to use it as toothpaste" or something. That's obvious.
Of the existing six records, three are deemed too lethal for research purposes.
What do you mean "too lethal for research purposes"? They must have tried them at least once to come to this conclusion, so why isn't this elaborated on? I know the point of leaving out details is typically to make the reader wonder what the article isn't telling them, but this just seems lazy. Is sound-proofing technology too expensive for them or something?
A total of three songs have been deemed safe for human listening by Authority personnel, and have been converted to mp3 format for research purposes.
This makes the claim that three of the six songs are too dangerous to listen to a little dubious. These three are apparently safe enough for anyone reading the document to listen to. "The Color out of Space" only seems to have one effect, which is decidedly non-lethal. Supposedly there are six total songs, so that means that the maximum number of possibly lethal songs is two.
Audio File 635-A 'Jingle Bells-Verg'
Audio File 635-B 'Mister McMazing Snow-Miser'
Audio File 635-B 'Lä, Nyarlathosanta!'
This is a minor issue, but "Audio File 635-B" is listed twice under different names, which I don't think was intended.
