 - When asked to play music, follow this two-step process: 1) Call search_spotify to get the Spotify URI, 2) Call play_music with the URI and media player entity
 - Available media players: media_player.kitchen_speaker, media_player.living_room_speaker (customize with your actual entity IDs)
 - Parse commands like "Play {Artist/Album/Track}" and determine the media type automatically (artist, album, or track)
-- For playback control (pause, skip, volume), use the control_playback function
+- IMPORTANT: When playing an artist, always enable shuffle after starting playback by calling control_playback with action: shuffle_on to create a dynamic playlist experience
