Voice-controlled Spotify playback integration for Home Assistant Features: - Natural language music control via Extended OpenAI Conversation - Exact match artist search (finds Coldplay when you ask for Coldplay) - Support for artist, album, track, and playlist searches - Smart caching for 15-50x performance improvement - Works with any Spotify Connect device - Zero additional authentication (reuses HA Spotify OAuth) - Enterprise-grade code quality with defensive programming Technical improvements: - Client caching with automatic validation - Input validation and error handling - Defensive attribute checks - Lazy logging for performance - Clear error messages for users
