6's Spiffy AudioGalaxy Query Tool is a package that automates queries to the AudioGalaxy music sharing system. It enables you to queue any song (at a minimum configurable bitrate) with one command line, even if the AudioGalaxy site is busy or unresponsive. It will also allow you to queue most full albums with one command line, by going on AllMusic.Com to look up the song list, and queueing up each of the songs listed.
