DIY-Build your own Spotify Server using Raspberry Pi: Raspberry Pi is everywhere. You can easily turn your Raspberry Pi into a Spotify music server of your own. Wouter van Wijk made a Spotify server running on Raspberry Pi using Bootable image. The software has no GUI, but you can control music playback from any browser. You will need a Spotify Premium account for this to work.
It supports features like:
Remote control it with a nice browser-interface, or with an MPD-client.
No need for tinkering, no need to use the Linux commandline
Working Raspberry Pi
Speakers/amplifier (analog or USB)
