Run Devil Run

Ke$ha - Run Devil Run

SNSD - Run Devil Run

Story behind:
The song was composed internationally by Busbee of USA, Alex James of UK, and Kalle Engstrom of Sweden. Ke$ha has recorded a guide version before her debut because of her close relationship with one of the composers. Guided versions are recorded songs (usually by a different artist or non-artist) to help in sound recording, with usually no intentions of official releases by the recorder. Ke$ha's guided version was leaked onto Youtube and action was taken to delete them, but some still remain. SNSD is considered the official artist of the song, "Run Devil Run".
