For best results, be clear and ask for exactly what you want - vague or contradictory prompts can confuse the AI and may return an empty playlist. Include a seed track (ideally 1–3), because the system infers the vibe—genre, era, energy/tempo, instrumentation from the seed and aligns it with your description. Use concrete cues like “night driving, synthwave, 100–120 BPM, no vocals,” and make sure you actually have songs in your library that fit the genre or vibe you’re asking to sort (if you request Afrobeat but don’t have any Afrobeat tracks, the playlist may come back empty).
