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.

MusicBrainz Picard is a revolutionary music sorting software developed by MetaBrainz Foundation, it's free, open-source and cross-platform. First use of it, maybe you feel its UI is so weird, but once get started, you will find that's really reasonable and user-friendly.
