A test sound in a build 1.1 prototype testing music/coding in the game. It also used again in build 1.2 as a test loop. The first version you hear is the sound in prototype build 1.1 and the second version you hear is the sound loop test by an alpha tester in Scratch 3D. Also one of the sound loops in the japanese version of Scratch 3D called "Enka" in Japanese or "Sakura" in the Japanese English version.
