notch - calm4/Magnetic Circuit
Calm4.ogg was a music file (alongside the other tracks) that was beta-tested and created by Notch himself. It consists of an up-beatbattle-like tune. A part of the song has Notch saying "Mojang Specifications" in a slowed-down voice. The track was released around Alpha 1.1.1 (Seecret Saturday 10)but it is unknown when and why it was omitted from the downloaded game files.
