Delete songs and other items in Music on Mac
In Music on Mac, delete songs, playlists, folders, and other content. You can remove the items from your library or from your computer.
In the Music app on your Mac, click Songs in the sidebar on the left.
Select the item you want to delete, press the Delete key, then click Delete Song.
Do one of the following:
Remove the item only from your library: Click Keep File.
Delete the item from your computer: Click Move to Trash. The item is removed the next time you empty the Trash.
Note: If the song was immediately removed from your library (that is, you didn’t get the option to keep the file or move it to the Trash), you can add and download it from Apple Music again.
If you can’t remove a song, make sure you didn’t select a song in a Smart Playlist with “Live updating” turned on.
