MediaMonkey
MediaMonkey is an easy-to-use music manager and media jukebox for serious music collectors and iPod users. It catalogs your CDs, OGG, WMA, MPC, FLAC, APE, WAV and MP3 audio files. It looks up missing Album Art and track information via Freedb and the web, and includes an intelligent tag editor... Its player automatically adjusts volume levels so that you don't have continually fiddle with the volume control and supports hundreds of Winamp plug-ins and visualizations along with a Party Mode for use in public places; or if you prefer, it can use Winamp as the default player.
