The prompt

A tender orchestral pop track with driving energy and a swung feel at 152 BPM. The low end is electric bass playing root-note anchored, under an acoustic drum kit with a tight and dry snare and sparse dark cymbals. Grand piano carries the harmony, fingerpicked. The arrangement follows AABA. A full-voiced female vocal delivers a smooth and melismatic performance. Analog hiss adds texture, with a slapback delay on the vocal. Mixed in a clean and spacious style, foregrounding harmonic warmth and atmospheric space, built on chromatic and shifting chords, leaving a calm and settled atmosphere.

Paste this into any style field. It describes the sound only — adjust anything that does not match what you are after.
