The Free Music Archive (FMA) is an online repository of royalty-free music, currently based in the Netherlands. Established in 2009 by the East Orange, New Jersey community radio station WFMU and in cooperation with fellow stations KBOO and KEXP, it aims to provide music under Creative Commons licenses that can be freely downloaded and used in other works. The service launched with an emphasis on curating high-quality works in a manner "designed for the age of the internet". Users can also "tip" musicians via donations.
