Your query should return all songs from the artist "Queen" which is currently does, but you had to look and find all the titles and add them to your query individually. So, although these songs are from that artist, your query should work without having to modify it if you add another song from Queen.

Assume that there are thousands of songs, and you want to display all songs from a particular artist. You wouldn't want to look through all the songs to find the titles of each one and build your query. You want to tell the computer to show you all the titles for the particular artist.
