Song ID3 refers to an audio metadata tag, which is used to store and describe the related information of audio files. It can contain information such as song name, singer, album, release year, lyrics and cover, which is convenient for users to view and search songs in the player or music management software.

ID3 tag is an indispensable part of the network music era, especially for people who like listening to songs. When downloading songs on the Internet, ID3 tags can make users easily get information about songs, and at the same time, they can also manage audio files better.

Adding ID3 tags can help us manage songs and enjoy music better. To add ID3 tags to songs, you can use an independent ID3 tag editor, or use some music management software, such as iTunes and Windows Media Player, to directly import songs and add tag information. After tagging, we can manage our music files better and find our favorite songs more easily.
