"Faxing Berlin" is a progressive houseinstrumental written, produced and performed by Canadian record producer and DJ deadmau5. It is the first single from his third studio album Random Album Title, as well as his first ever single. On July 23, 2007, "Faxing Berlin" became the first ever release on deadmau5's label mau5trap. The track was originally known as "Da Outer Limits", but was then changed to "Faxing Berlin" later on.
In 2008, an artist called DirtyCircuit claimed to have been threatened with legal action after using the sample "LP_Faxing Berlin C_128bpm" that came bundled with FL Studio, which deadmau5 claimed copyright for. The sample was a direct clip of a full bar of the song. deadmau5 provided a demo track which came bundled with FL Studio, along with several loop samples. The case caused a slight discomfort among the users of FL Studio, some of which have pointed out potential inconsistencies in the EULA of the software.
