Short answer: don’t use consumer apps (Spotify, Apple Music, Amazon Music, YouTube Music, etc.) in a spa — use a commercially licensed “music for business” service (or obtain public‑performance licenses from the PROs). (support.spotify.com)

Why: playing music in a public/commercial space requires public‑performance licenses (ASCAP, BMI, SESAC, GMR in the U.S.). Consumer streaming subscriptions explicitly cover personal use only and do not include those public‑performance rights. You can either (A) subscribe to a business music provider that handles the licensing for you, or (B) buy the required PRO licenses yourself. (bmi.com)

Common licensed business music providers suitable for a spa (examples):

• Soundtrack (formerly “Spotify for Business”) — licensed for commercial use and built for retail/venues. (soundtrackyourbrand.com)
• SoundMachine — background‑music service with PRO coverage for the U.S./Canada. (sound-machine.com)
• SiriusXM / Pandora for Business (Pandora CloudCover / SiriusXM Music for Business) — commercial plans that include required licensing. (pandora.com)
• Rockbot, Mood Media and similar background‑music companies — they explicitly state they cover PRO licensing for music played through their service. (rockbot.com)

Practical steps for a spa owner

1. Choose a business music service that explicitly says it includes ASCAP/BMI/SESAC/GMR public‑performance coverage. (That’s how you stay legal.) (soundtrackyourbrand.com)
2. Confirm the service supports features you need for a spa: ad‑free playback, offline/house‑music for treatment rooms, scheduling/dayparting, volume zoning, and explicit‑lyrics filtering. (Most business services list these features.) (soundtrackyourbrand.com)
3. Keep your subscription records and any reporting the provider gives you (some providers report plays to rights organizations on your behalf). (soundtrackyourbrand.com)
4. If you prefer not to use a provider, contact the PROs (ASCAP, BMI, SESAC, GMR) to purchase the proper public‑performance licenses for your location — this is more work and can still require multiple PROs. (bmi.com)

Cost note (examples): business music plans often run roughly $15–$35+ per location per month depending on provider and features; enterprise pricing is higher. Check each provider for current rates and any hardware/player needs. (pandora.com)

If you want, I can:

• compare 3–4 specific business music services side‑by‑side for spa use (features, price, offline support), or
• pull up the exact licensing statement for any particular provider you’re considering.
