For people who like to listen to music, there must be a lot of music files on their hard disk. As the number of music files grows, the music management becomes more inconvenient and inefficient. For example, many files lack ID3 tags or have incomplete information, which makes it very difficult for users to know exactly the artist's name or even the title of a song. In this case, the music player does not display the song information because it cannot read the metadata of this song.

In many cases, the song name, singer information, album cover and other song information of music files downloaded from the Internet are chaotic or missing. For users who like to download and collect songs, this is really a headache to manage such a music library.
