 ## Response Key
 Some API responses are wrapped in a top level object like `artists` or `tracks`. If you want to directly access the content of a given top level object, you may do so by passing its key as a string to the `get()` method.
 
 ```php
 // This will return the content of the tracks object.
-Spotify::searchTracks('Closed on Sunday')->get('tracks');
+Spotify::searchTracks('query')->get('tracks');
