Cowbell is an elegant, album-based, music organizer written by Brad Taylor in C# for Gtk+. Using TagLib, it supports many audio formats including: - Ogg/FLAC - MP3 - MusePack Cowbell is tightly integrated with Amazon.com using its free SOAP service. Cowbell employs this service not only to fetch album cover images, as most tag editors do, but also in combination with intelligent algorithms to "guess" the appropriate song information from song titles. It can also cache these cover images in the same directory where that album resides. For you console junkies, Cowbell also offers a command-line based batch tagger which can tag and "guess" a whole collection of music with just a few keystrokes.
