Item #: SCP-3869
Object Class: Euclid
Special Containment Procedures: Mirrors of the websites YouTube and Bandcamp are to be hosted on an isolated server farm located on Site-15. Foundation agents implanted in internet service providers around North America are to monitor web activity from the 203.0.██.███ family of IP addresses. When the public instances of the aforementioned sites are requested by these addresses, they are to be redirected to the foundation-hosted mirrors.
Description: SCP-3869 is an anomalous YouTube channel by the username "Mr. High Quality." The videos on the channel feature still images of video game logos, as well as music playing in the background (hereafter SCP-3869-1) which functions as a low-grade cognitohazard. Instances of SCP-3869-1 often vary greatly from the music that the upload titles and descriptions claim them to be, and are at times wholly unrelated to the original piece.
SCP-3869's anomalous properties manifest when an instance of SCP-3869-1 is opened and allowed to play, at the minimum, to the point where the instance diverges from the original track. If an affected subject engages with the video game from which the SCP-3869-1 instance is claimed to originate, the audio from SCP-3869-1 will replace the original track within the game through anomalous means. At this point, secondary anomalies will manifest, often relevant in nature to the edits featured in the anomalous video. Though the primary anomaly can be observed regardless of prior exposure to SCP-3869-1, the replaced music in the context of the game does not act as its own instance of SCP-3869-1.
Addendum 3869-1: On 05/22/17, the "channel description" area of SCP-3869's profile, which was previously blank, updated to contain the following text.

Addendum 3869-2: Unless otherwise indicated, testing was carried out featuring an unmodified version of the game in question, on an unmodified version of the relevant platform. For each test, one D-class was exposed to SCP-3869-1 before testing, and one was used as a control group.

Test 1
SCP-3869-1 instance title: Overworld - Super Mario Bros.
Differences from original track: Vocal track added, identified as "Drop It Like It's Hot" by Snoop Dogg, edited to match the tempo of the background track.
Test results: Subject became easily agitated by discussion related to the use of narcotics, but personality remained otherwise unchanged.
Miscellaneous notes: After testing, subject expressed frustration with a nonfunctional door supposedly encountered in the game. There are no doors in Super Mario Bros.

Test 2
SCP-3869-1 instance title: Snake Eater - Metal Gear Solid 3: Snake Eater
Differences from original track: Vocals recreated with poorly-modulated text-to-speech software.
Test results: Subject's voice replaced with one bearing striking resemblance to poorly-modulated text-to-speech software.
Miscellaneous notes: N/A

Test 3:
SCP-3869-1 instance title: Let's Go Shopping (Beta Version) - PAYDAY 2
Differences from original track: All tones produced by the lead synth normalized to the note of C3.
Test results: Inconclusive.
Miscellaneous notes: Testing concluded that the different "versions" of a song are indicative of a non-standard context. Beta version of PAYDAY 2 could not be secured for further testing with this instance.

Test 4
SCP-3869-1 instance title: Last Surprise (OST Version) - Persona 5
Differences from original track: Continues normally until the first line of the chorus, during which the vocals cut out mid-sentence, and the image in the video cuts to a blank screen.
Test results: Subject reported vision rapidly degrading at the point of divergence from the original song, resulting in total loss of eyesight. Blindness persisted after playback was stopped.
Miscellaneous notes: Anomalous effects did not activate while playing the game in question, and instead manifested while playing an album featuring the game's original soundtrack. This confirms the hypothesis posited after Test 3.

Test 13
SCP-3869-1 instance title: BFG Division - DOOM (2016)
Differences from original track: Japanese vocal track added, belonging to a separate, unidentified song, which does not match the instrumental in key, tempo, or time signature.
Test results: Subject reported a steady, continuous increase in ambient temperature despite the control subject reporting no such alteration. By the time the duration of the song had elapsed, the subject lost consciousness, displaying symptoms analogous to frostbite. The onset of hypothermic symptoms was slowed, but not reversible through conventional means until 3-4 minutes after the song stopped playing in the game. Subject likely would not have recovered without direct intervention.
Miscellaneous notes: Control subject played game while exposed subject watched. Control subject experienced no adverse effects. Replacement phenomenon found not to act on its own as an instance of SCP-3869-1.

Test 20
SCP-3869-1 instance title: Slow Ride - Guitar Hero III: Legends of Rock
Differences from original track: Track gradually slows down to a minimum of 25% of original speed.
Test results: Subject reaction speed increased at a rate consistent with song's reduction in tempo. Testing stopped before the song could play to completion, but effects continued even after the console was unplugged. Subject expressed anxious behavior before attempting to escape. Subject moved at superhuman speeds, and avoided small arms fire from security team, but ultimately collapsed from a grand mal seizure. Subject's heart rate rapidly increased until chest cavity exploded after █ minutes of unconsciousness.
Miscellaneous notes: Testing put on temporary standby.

Addendum 3869-3: On 5/30/2017, the Foundation took notice of a video on SCP-3869 determined not to be cognitohazardous in nature. Instead, it directed the viewer to a page on Bandcamp, which featured an album of self-proclaimed "Greatest Hits" from the channel available for free download. The Foundation secured the album in .zip form before taking the page down. Containment protocols updated to include a locally-hosted mirror of Bandcamp in addition to the existing YouTube facsimile.
The tracks on the album also function as effective instances of SCP-3869-1, with the difference that the tracks, rather than being attributed to the source game's composer, are attributed to various miscellaneous usernames, likely the users who contributed the song edits; this would mean that SCP-3869 is not the work of an individual, but rather a collaborative project. Further analysis indicates that the authors credited on the album do not match any known users found in any Gamers Against Weed chat logs in the Foundation's possession.
Along with the listed tracks on the album, an additional password-protected archive labeled "heyjude.zip" (detailed in Document SCP-3869-A) was included inside the album's own archive.
Addendum 3869-4: The following is an excerpt from existing chat logs stored on the Foundation database, found to pertain to SCP-3869, from a private chat room hosted by GoI-#5869 "Gamers Against Weed."

bluntfiend: Okay, let's put this one to rest once and for all.
bluntfiend: Gun to your head, which would you rather have on a pizza instead of real cheese: Velveeta, Easy Cheese, Cheez Whiz, or Kraft Singles?
FBI_Official: I'd take the bullet
lesbian_gengar: jude, what the fuck.

tacticalCannabinoid: mr. high quality
bluntfiend: This is the first I've heard of a "Mr. High Quality."
bluntfiend: And as far as I can tell, we aren't starting a new series of Misters when we really haven't even finished the first yet.
bones: Not seeing anything like that in a quick search of the older logs.
tacticalCannabinoid: https://youtube.com/channel/█████████████
FBI_Official: You'd think someone would've mentioned it here or at least said something cryptic
FBI_Official: Lemme see
lesbian_gengar: this is some downright amateurish shit here, really.
lesbian_gengar: they didn't even get the "misters against weed" format right.

tacticalCannabinoid: ok we can pick their style apart all day long but our names are on shit that we dont want our names on
FBI_Official: Well, judging that some of the uploads have already been taken down via copyright strikes from "Smith Copyright Protection"
FBI_Official: Sounds like it's gonna be the Janitors' problem sooner rather than later
bluntfiend: If it's who I think it is, I almost can't help but feel sorry for these guys.
bluntfiend: …Only almost, though.
lesbian_gengar: in that case we should probably be on our guard just in case they try to pin it on us.
tacticalCannabinoid: good idea
FBI_Official: Ye
polaricecraps: zoned out for a bit
polaricecraps: but ftr i'm going with velveeta
