Musicshake
Musicshake is a Korean web service that allows the general public without any knowledge of music to create their own music with simple steps/clicks based on more than half a million different ‘modules’.
The company is headquartered in Seoul, South Korea with US offices in Los Angeles, California, and uses its proprietary technologies to provide an application that can be used to combine different music samples to create unique tracks that can be downloaded as MP3. The application itself can be downloaded from the website and music creation is also free, but the company charges a fee for MP3 download. Musicshake uses its own virtual currency called Shake Cash.
