I'm not doing this feature because it's complicated to delete an artist. An artist may be related to an album with multiple artists. If you delete the artist, should the album be deleted as well? This is not good. The same conflict occurs when deleting a song. Should the album of the song be deleted as well? Therefore, my decision is:

1. Album songs cannot be deleted. You can only delete the album and delete all the album songs.
2. Artists cannot be deleted. They will be automatically deleted if they have no song.
