Apple Music is an audio player that supports several audio formats, allows you to purchase music via the iTunes Store, and can play over 75 million songs with a subscription to the Music streaming service. Apple officially replaced the iTunes audio player with Music when it released macOS Catalina (version 10.15) in October 2019.

You can find the MUSICLIBRARY file in the following location:

/​Users/​username/​Music/​Music/​Music Library

macOS does not display the .musiclibrary file extension for the "Music Library" package. However, if you right-click the file and select Get Info, you can verify the .musiclibrary file extension in the "Name & Extension" field.

NOTE: If you delete the "Music Library" file, Music recreates it by searching for songs in the Music folder. However, all playlists, song ratings, and preferences will be lost.
