So what has this device got to do with Linux or Unix? Perhaps a unique feature of the Squeezebox is that the server software, which controls the device and streams music to it, is completely open source; it is released under the common GPL (Gnu Public Licence), and it works just as well on a Linux (or Unix) system as it does on Windows.
The software is written entirely in Perl, which is supplied on every non-specialised Linux distribution as standard. The Squeezebox can itself decode mp3, wmv and Flac files in its hardware.
