Delete Music from Your Music Library
Music files can be deleted from your music library from a web browser on your computer.
To delete music from your music library, do the following:
Go to Your Music Library .
Check the box or boxes next to each file you want to delete.
Tip: To select multiple songs to delete at the same time, check the box next to the first song you want to delete, press and hold the Shift key on your keyboard, and then check the box next to the last song you want to delete. This automatically highlights and selects all of the songs in between the two.
To confirm you want to permanently remove these files from your music library, click Delete.
