WMP Tag Plus is a plug-in that seamlessly integrates into Windows Media Player, providing library and tagging support for additional music formats including Ogg Vorbis, FLAC, WavPack, Monkey's Audio, Musepack, and MPEG-4.
After installing WMP Tag Plus, Windows Media Player adds songs of the newly supported formats into its media library, including the tags these songs contain. When editing the tags of these songs in the library, changes are saved back to the file. This function means that you can painlessly browse and organize songs for newly supported formats in the library, just as you would with songs of natively supported formats like MP3 or Windows Media Audio (WMA).
Also, you can use the Advanced Tag Editor to edit tags for any newly supported formats. Windows Media Player 12 lacks the Advanced Tag Editor, but you can use the new tag editor of the Windows Media Player Plus! Plug-in to get the same result.
WMP Tag Plus is one of the only Windows Media Player tag support plug-ins still up-to-date, actively supported, and compatible with the latest versions of Windows and Windows Media Player.
