The m3u playlist format is recognized by many music players, including Winamp, Windows Media Player, and others.
If you have a large music library containing artists from many different genres sorted alphabetically like many people do it can annoying to queue up music that is only in the genre you're in the mood to listen to. The Genre Playlist Builder solves that problem by searching the songs of your music collection for their genre and letting you generate playlists for a single type of music. No more wading through all that death metal, klezmer, and reggae when all you want right now is some classical music to listen to.
