Magnetic Circuit, better known by its filename calm4.ogg, was a track briefly included with one version of Minecraft in September 2010.

Info
This track was accidentally included with Java Edition Alpha v1.1.1 where it was being used for testing of a newly implemented music system. It was not included with v1.1.2 or any later versions, but the file would never be overwritten by downloading any later versions, and as the game would play any ogg file in the music folder, players who had previously downloaded v1.1.1 (or who had otherwise placed the file into the directory) would still be capable of hearing it in later versions, up until the 1.6.1 launcher's introduction, which ends up forbidding it from being heard even in older versions due to music being downloaded and stored separately.

Playback
Magnetic Circuit would play randomly during general gameplay, like with other background music at the time.

Composition
The song is in the key of D-sharp minor, with a time signature of 4/4.

At 1:03 and 1:36, "Mojang Specifications" can be heard
