Week: 2026-03-23 → 2026-03-29
Growth Drivers
  • Surface concentration: Mixed surfaces
  • Momentum (72h): median 27.0 attention observations per title
  • Market activity: 98 observations across 5 titles
Analyst Notes
  • GXI score: 47.7 (0–100).
  • Signals observed: 98.
  • Territory mix: US leads (64.3%). Top countries: US, FR, CA.
  • youtube is currently capturing 89.8% of measured weekly discovery activity. Cycle state: Acceleration. Median 72-hour velocity: 27.00. Interpretation confidence: High confidence. Discovery is overly dependent on youtube, which increases fragility. Short-form replay and share loops are likely to strengthen before deeper listening conversion catches up.
  • Dominant signal types: mirror.

What this week indicates

This weekly build is designed to show not just where attention exists, but where next-stage demand is most likely to form, which surfaces are actually carrying the title, and what intervention windows matter before momentum diffuses or gets captured inefficiently.

Top 5 Expansion Titles

Title-level intelligence on where discovery is concentrating, what likely happens next, and which interventions can improve conversion efficiency.

#1 — "Superbloom" - by Jessie Ware (Country: US)

  • Signals: 29
  • Primary discovery surface: youtube
  • Surface share: 86.2%
  • Cycle state: Acceleration
  • Interpretation confidence: Good confidence (79/100)
  • Estimated 30-day attention value band: $1,891.41–$3,438.94
Surface mix:

youtube2586.2%
seo_spam26.9%
apple13.4%
Executive framing:
youtube is currently capturing 86.2% of measured weekly discovery activity. Cycle state: Acceleration. Median 72-hour velocity: 27.00. Interpretation confidence: Good confidence. Discovery is overly dependent on youtube, which increases fragility. Short-form replay and share loops are likely to strengthen before deeper listening conversion catches up.
Why this matters:
For music, replay, shareability, and creator reuse often accelerate before deeper listening conversion appears cleanly in native platform analytics.
Next likely outcome:
Short-form replay and share loops are likely to strengthen before deeper listening conversion catches up.
Signal quality notes:
  • Dominant signal types: mirror
Recommended interventions:
  1. Protect the lead surface first: publish one native-format asset for youtube within 24–48 hours.
  2. Route paid and organic traffic into one owned conversion path instead of splitting attention across weak destinations.
  3. Do not over-diversify yet. Concentrate around the current lead surface while discovery is still coherent.
  4. Use short-form loop creative, pre-save or stream routing, and a replay-friendly CTA to convert discovery into repeat listening.
  5. Treat this as an active intervention window, not a reporting window. Move in hours, not next week.

#2 — "Reverie " - by Lolo Zouaï (Country: FR)

  • Signals: 27
  • Primary discovery surface: youtube
  • Surface share: 96.3%
  • Cycle state: Acceleration
  • Interpretation confidence: Good confidence (76/100)
  • Estimated 30-day attention value band: $1,760.97–$3,201.77
