 * Exercises for the reader
 
-  - Defining new interactive commands for other types and queries,
-    as well as standard filters.
-  - Pagination when we receive more than the standard 20 results.
-  - Metadata set for Marginalia.
+  Defining new interactive commands for other types and queries,
+  as well as standard filters shouldn't be too complicated now that we
+  have the above tools at our disposal.
+
+  For instance:
+  #+begin_src emacs-lisp
+     (defun consult-spotify-playlist (&optional filter)
+       (interactive)
+       (espotify--maybe-play (consult-spotify-by 'playlist filter)))
