Item #: SCP-CN-180

Object Class: Euclid

Special Containment Procedures: SCP-CN-180 is currently contained in a safe in a Low Security Containment Unit at Site-CN-71. Only personnel with Level CN-180/3 clearance or higher are allowed to access the object. When not being experimented on, SCP-CN-180's BPM setting is to be set to the lowest possible value. In the event of an accident in which SCP-CN-180 plays at any other BPM setting, or plays at its lowest BPM setting for more than 85 seconds, Protocol CN180T4 is to be enacted immediately.

Description: SCP-CN-180 is an MP3 player measuring 5cm x 2cm x 1cm of unknown make and model, with "SPEEDCORE GENERATOR!!!" written on its reverse side in unremovable red ink. There is no headphone jack or charging port on the device, only "play/pause" and volume buttons below a LCD screen. SCP-CN-180 has been on since being acquired, and no means of turning it off have been found, nor any means to exhaust its battery.

SCP-CN-180's LCD screen continuously displays the label "BPM" and three digits, henceforth referred to as the BPM setting. The BPM setting can be changed using the volume buttons, but seemingly cannot be lowered below 540 a certain BPM. The minimum BPM setting is correlated to the current physical location of the object. When the "play/pause" button is pressed, SCP-CN-180 will play a track with heavy bass on loop at a volume over 100 dB until the "play/pause" button is pressed again, with the track's tempo matching the BPM setting.

After Incident CN-180-Alpha, SCP-CN-180 has been discovered to affect humans' activities within a nearby area. Human subjects within SCP-CN-180's range of effect appear to have their daily routines altered. Upon experimentation, it was discovered that SCP-CN-180's BPM setting is correlated to its effects on humans. When played at minimum BPM setting, there is no visible alteration. Effects of increasing SCP-CN-180's BPM setting consist of but are not limited to:

- Increased eating speed
- Increased rate of speech
- Increased rate of work
- Decreased motor finesse
- Increased rate of movement
- Decreased time spent asleep
- Decreased patience when waiting for long periods of time
- Increased metabolism

The range of SCP-CN-180's effects increase as it is allowed to play for extended periods of time. Whether one is able to hear SCP-CN-180 does not appear to affect whether one is affected by SCP-CN-180's anomalous effects.

SCP-CN-180 was bought from a second-hand electronics store in Mong Kok, Hong Kong SAR by Agent ███ █████████. It was identified as an anomalous item due to it not requiring recharging and only being able to play one track. However, after Incident CN-180-Alpha, its true anomalous effects were discovered and it was reclassified as Euclid.

Incident CN-180-Alpha: On ██/██/20██, during maintenance of its chamber, SCP-CN-180 was activated for 5 seconds with a BPM setting of 850 due to a mistake on the part of maintenance personnel, before being turned off. After maintenance was completed, the maintenance personnel reported that the rate at which work was carried out increased drastically during the period when SCP-CN-180 was playing. Upon reviewing security camera footage, the maintenance personnel had completed three tasks that were projected to take one minute to complete in the span of five seconds. These tasks were later discovered to have been performed sloppily and had to be redone. In addition, personnel near SCP-CN-180's chamber were seen to walk noticeably faster. Upon discovering this, SCP-CN-180 was given SCP designation and classified as Euclid.

Appendix CN-180-A: During a containment failure, SCP-CN-180 was transferred to Site-CN-██, at which point staff discovered that SCP-CN-180's BPM setting could be lowered to ███, lower than what was previously considered the minimum. Upon further testing, SCP-CN-180's minimum BPM setting was discovered to change between different locations. Testing is underway as to how these variables are correlated.
