Case Study

How a billion-stream catalog cut costs by 79% while scaling to 200+ campaigns

The Challenge: Scaling to 200+ Campaigns Without Losing Efficiency

Promoting a growing, billion-stream catalog meant running well over 200 campaigns without letting cost per result drift upward as volume scaled. The goal was to turn individual campaign learnings into a single, repeatable strategy applied catalog-wide.

The Solution: Quarterly Business Reviews

A structured quarterly business review with top management paired campaign-after-campaign optimization with account-wide strategy decisions, so every learning fed directly into the next quarter's playbook.

Campaign Settings
Catalog-Wide Cost per Result Reduction
Q1 2025 – Q2 2026 (6 quarters)
Multi-market
Multi-genre (full catalog)
Spotify / DSPs (via Ctrl+Reach)
Campaign Results
-79%
Cost per Listener Result ($0.678 → $0.145)
+367%
Listener Result Efficiency (1.48 → 6.89 results per $1)
38.6M
Streams Attributable from Ads (28-day attribution window)

Weighted Cost per DSP Result, Quarter After Quarter

Applied consistently across the catalog, the weighted cost per DSP result improved campaign after campaign:

  • Q1 2025: $0.477
  • Q2 2025: $0.529
  • Q3 2025: $0.360
  • Q4 2025: $0.346
  • Q1 2026: $0.144
  • Q2 2026: $0.145

Overall: -79% cost per listener result ($0.678 → $0.145), and a +367% gain in listener result efficiency (1.48 → 6.89 results per $1).

The Result

Over the analysis period, the catalog generated 38.6M streams attributable to ads within a 28-day attribution window, with stream growth accelerating since adopting Ctrl+Reach compared to the prior year's organic trend.

All figures measured in Ctrl+Reach campaign tracking across DSP campaigns in the analysis period.
