What are ID3 Tags?

ID3 tags are information about an MP3 file, such as the Artist, Album, Title, Year, Track, Genre, and Length of the track. ID3 tags are optional information that can be added when the MP3 file is created. If the MP3 file was created using any or all of an ID3V1 or ID3V2 tag information, FreeAmp retrieves and stores the ID3 information for the track in a type of database. Using this information, you can sort your Playlist by any of the ID3 tags FreeAmp found for that track.
