+This example uses an [`input_select`](/components/input_select/) element to pick which mp3 file to play on a [Chromecast](components/media_player.cast/).
+
+```yaml
+# Define our dropdown list
+input_select:
+  lullaby:
+    name: Lullaby
+    options:
+      - Rain
+      - Babbling Brook
+      - None
+    initial: None
+    icon: mdi:weather-rainy
+
+# Define our media player
+media_player:
+    - platform: cast
+      host: chromecast-nursery
+      name: Nursery
+
+automation:
+  # If you select "Rain", play the "rain.mp3" file
+  - alias: Play Rain Lullaby
+
+    trigger:
+      platform: state
+      entity_id: input_select.lullaby
+      to: "Rain"
+
+    action:
+      service: media_player.play_media
+      data:
+        entity_id: media_player.nursery
+        media_id: http://fileserver/rain.mp3
+        media_type: audio/mp4
+
+
+  # If you select "Babbling Brook", play the "babbling_brook.mp3" file
+  - alias: Play Babbling Brook Lullaby
+
+    trigger:
+      platform: state
+      entity_id: input_select.lullaby
+      to: "Babbling Brook"
+
+    action:
+      service: media_player.play_media
+      data:
+        entity_id: media_player.nursery
+        media_id: http://fileserver/babbling_brook.mp3
+        media_type: audio/mp4
+
+  # If you select "None, turn the Chromecast off
+  - alias: Stop the Lullaby
+
+    trigger:
+      platform: state
+      entity_id: input_select.lullaby
+      to: "None"
+
+    action:
+      service: media_player.turn_off
+      data:
+        entity_id: media_player.nursery
