How I Built a Pop Star from a Spreadsheet

1
Data
Build the Index

What actually makes a pop star last? Not who's biggest right now, but who endures. I built the Pop Star Iconicity Index — a scoring model that ranked 300+ artists across four dimensions: ChartScore, SpotifyScore, TikTokScore, and IGScore.

Analysis
Find the Patterns

I spun up a ChatGPT o1 Deep Research query to analyze what the top-scoring artists share — the creative patterns that separate icons from one-hit wonders. It identified the target archetype: “solo female voice only. Female pop star like Billie Eilish, Sabrina Carpenter, and Taylor Swift. Alt-pop with indie and synth-pop influences.”

Identity
Design the Artist

I used the archetype patterns to generate AI visual prototypes, then ran a Google Form survey. One prototype got 36.4% of the votes. The name had to be short, sticky, and memorable: Juno Grey.

Production
Make the Music

I fed the index-derived prompts into Musicful.ai and iterated until the output felt like a real artist with a real point of view — not playlist filler. The result was the debut album: The Greylist.

Visual
Make the Videos

Velvet Static (3:22): 74% AI-generated using Adobe Firefly and Sora, 26% Pexels stock footage. ~10 hours. Lip-sync failed spectacularly. Used to Miss You: Sora rejected photorealistic Juno Grey — it thought she was a real person. Pivoted to animation. All free-tier Sora, 4–12 second clips spliced in iMovie. Key insight: describe around the subject. “South Park without saying South Park.”
