The desktop organization of music is primarily embedded into audio players and media players like Amarok, Rhythmbox, Banshee, MediaMonkey, Songbird, Apple's iTunes and Microsoft's Windows Media Player or Zune. Organization is used to create playlists, or to organize the media collection into a folder hierarchy, by specific artists, albums, or genres. Another type of the music organizers allows user to organize his media collection directly without listening of music. By connecting the audio players to databases of tagged music to compare a collection with a professionally organized and tagged collection of music, MP3 collections can be enhanced with metadata corrections to support the organization process when metadata is not complete in the original items.
