Music Tag analyzes your music library and downloads missing artwork and track data directly to your music files. Modern music library software like iTunes and Windows Media Player or potable media players like iPod use information embedded in your music files to correctly catalogue your music library. But what happens when that information is incorrect or missing completely? Music Tag uses advanced digital fingerprinting technology to identify your music and then downloads the correct artwork and other data like track Title, Artist, Album and more. Music Tag saves this information in your music file where it can be accessed by music library software and portable media players.
