Legitmix is a Canadian company that offers services to artists who create remixes. The company has offices in Ottawa, Canada and Brooklyn, New York. and launched its product in 2011,
Legitmix sells a file that rebuilds a remixed song on a user's hard drive using the listener's copies of the sampled tracks. Remixers receive 70% of the price of their Legitmix files, while copyright holders get paid for the purchase of the original tracks used in the remix. Music files used to construct remixes must be exact matches to the ones legally sold through Legitmix. Because listeners are required to purchase or already own the original tracks used in a remix, the recreated remix might be several times more expensive than the cost of an individual song.
