Per 
Special Containment Procedures: SCP-XXXX is to be stored in a standard metal lockbox with at least five meters between the object and technology of any kind. The object is to be checked for impurity to be left alone, by executive order.
An instance of SCP-XXXX.
Description: SCP-XXXX is an anomalous, untitled vinyl record with no visibly anomalous properties that was discovered in Yekaterinburg, Soviet Union in 1970. When a subject plays SCP-XXXX in a record player of any type, it will output heavily distorted and aged versions of 1920's and 30's ballroom music. Each side only plays a singular, continuous track, that lasts anywhere from three minutes to three days. When subjects are exposed to the object's sound, they will begin to experience mental regression similar to that of victims of Alzheimer's, but in quicker succession. The damage the object causes to the brain is permanent, causing dementia-like symptoms regardless of age in minutes.
SCP-XXXX has the unique ability to copy itself into any type of audio recording device or play itself in audio listening devices within five meters of the record. These copies will spread themselves in the same manner, until they are not in the vicinity of any type of recording device. It is unknown how many copies of SCP-XXXX there are left in the world1. Despite significant challenges in recording a viable, non-anomalous copy of the record in full, attempts are underway have been successful have failed are discontinued2.
Testing Log XXXX
Entry Log 1
Subject: 50 year old male Class D personnel, with no prior family history of dementia.
Notes: Subject was ordered to place SCP-XXXX onto the vinyl player and then stop playback when they believed five minutes had elapsed. Subject was handed a 3x3 Rubik's cube, and told to solve it to the best of their ability. The completed time of the Side A was 12 minutes and 24 seconds.
Results: Subject quickly lost their dexterity and focus. Subject's cognitive awareness began to decline as the record started, which only worsened the further the record progressed. Five minutes elapsed without their acknowledgement. When the record's time had elapsed, Subject flipped the record to Side B, and resumed playback despite given no orders to do so. Guards entered with protective headphones and extracted both Subject and object without incident. Subject never regained lucidity. Subject euthanized. Plaques found at dissection in abundance within the finer areas of the brain gray matter.
The following is the output of SCP-XXXX, soundbyte has been identified as the song "Sweetheart of Sigma Chi" from 1933. Its anomalous effects removed through audio filtration.
Entry Log 8
Subject: 21 year old female Class D personnel, with no prior family history of dementia.
Notes: For this test, SCP-XXXX is rigged inside a record player which can be played remotely. Subject was given a pen and paper, and told to draw what thoughts that they might have. The completed time of Side B was 45 minutes and 12 seconds.Results: Subject showed signs of placation once SCP-XXXX began outputting noise. D-XXXX began drawing a generic family, as well as other objects associated with early adolescence. As the record progressed, D-XXXX began to draw symbols representing what appears to be Russian cyrillic alphabet. Examples include "очищение"3, and "ее термоядерное возвращение"4.
Subject remained visibly calm with no agitation or stress present whatsoever. Subject removed from chamber after attempting to continue playback on the opposite side of the disk. Cognitive tests showed that D-XXXX had the mental capacity of a twelve year old, and was able to follow basic requests but never regained lucidity. Subject euthanized. Dissection confirmed the abundance of plaques, most notably in the hypothalamus.
The following is the output of SCP-XXXX, soundbyte has been identified as "We'll Meet Again", released in 1939. Its anomalous effects removed through audio filtration.
Entry Log 15
Subject: 12 year old male adolescent civilian, with no prior family history of dementia.
Notes: Subject was placed in a testing chamber with SCP-XXXX inside a remotely controlled record player. The player would loop the disk to test mental endurance as in previous tests. The duration was 1 day, 14 hours, and 37 minutes.
Results: [DATA EXPUNGED]
Unidentified.
SITE-WIDE BULLETIN FROM THE O5 COUNCIL
I can't believe I have to fucking say this, but not for any reason do we allow child experimentation. I don't care, the answer is no.
Project Manager Adams has been detained and removed from her post. Project XXXX is suspended as of now, and an investigation is pending as to how, when, and who trafficked a civilian minor for experimentation. As for the disk, throw it under a damn lock and key. It works, people.
This kind of shit is zero-tolerance.
