What are music tags?

Music tags are the identity of a track

When you open a music file in a player, the app usually shows a title, artist, album, track number, genre, year, and cover image. Those details do not come from the filename alone. They are stored as metadata inside the audio file. This metadata is commonly called music tags.

A file named track01.mp3 can still display as a complete song if its tags are correct. In the same way, a file with a perfect filename can look messy in a player if the embedded tags are missing or inconsistent.

Common music tag fields

The most useful fields are title, artist, album, album artist, genre, year, track number, disc number, lyrics, and artwork. These fields help players group songs into albums, show the right cover art, and keep compilation albums from splitting into many separate artists.

• Title: The name of the song.
• Artist: The performer credited on the track.
• Album artist: The main artist for the album, useful for compilations.
• Genre: A category that helps filtering and playlists.
• Artwork: The embedded cover image shown by music players.

Why tags matter

Clean tags make a music library easier to search and browse. They also make songs look more professional when copied to a phone, synced to a media server, or played in a car system. Without good tags, the same artist can appear under several names, albums can split apart, and cover artwork can disappear.
