Spotify deprecated their Audio Features API in late 2024. We've replaced it with Google Gemini 2.0 Flash, giving you richer analysis that works for any song — not just those indexed by Spotify.

—BPM, key, time signature all technical parameters, same as before
—Genre + subgenre e.g., "Synth-pop / Retrowave"
—Mood descriptor e.g., "Nostalgic", "Energetic", "Melancholic"
—Song description 1–2 sentence musical character summary generated by AI
—Energy, danceability, valence feature bars AI-estimated from music knowledge
