Its called our "Loop Du Jour" (loop of the day) feature and these free loops can be used for your Flash projects, royalty free.
So if you havent found what you are looking for in the 200 loops we have already submitted to Flash Kit in the Sound Loops section, stop on by and grab a new music loop every day!
