Short answer — use a business‑licensed background‑music provider or a commercial/enterprise licence from a production music library (or a workplace plan from a focus‑music app). Don’t use personal Spotify/Apple Music/YouTube Music accounts for overhead/office playback — they’re licensed for private use only.

Where to find licensed focus playlists for offices (options)

• Soundtrack Your Brand — built specifically for businesses: ready‑made playlists (including “focus/ambient” types), scheduling, and a commercial license so you can legally play music in offices and lobbies. (soundtrackflow.com)
• PlayNetwork (and similar in‑store providers) — enterprise/office music programs that curate and license content for workplaces and multi‑location companies. Good for branded or lobby/overhead playlists. (playnetwork.com)
• Mood Media / Moodby / other background‑music vendors — turnkey licensed background music with curated channels for corporate/office atmospheres. (support.moodmedia.com)
• Epidemic Sound In‑Store and other production libraries — some libraries offer a business/in‑store product that covers commercial playback; note that their standard creator/video licenses often don’t permit standalone “listening” playlists, so use the specific in‑store/commercial offering. (epidemicsound.com)
• Production/stock music libraries (PremiumBeat, Audio Network, Motion Array, etc.) — buy business/“commercial” licences or enterprise packages and build custom instrumental/ambient playlists (useful if you want music without vocals or highly polished corporate cues). (premiumbeat.com)
• Focus‑music apps with team/workplace plans (Brain.fm, Focus@Will) — engineered/science‑backed focus audio; both offer team or workplace plans suitable for employee headphones and some enterprise deployments. Good for individual focus sessions or company subscriptions for staff. (brain.fm)

Quick picking checklist (to make sure it’s legal and suitable)

1. License type — confirm the plan explicitly covers public/commercial “background” or in‑store/office playback (public‑performance and master/composition rights). Providers above document this on their business pages. (soundtrackyourbrand.com)
2. Content style — look for “instrumental,” “ambient,” “lo‑fi,” “office,” or “focus” channels/playlists so music won’t be distracting or have explicit lyrics. (Most business services offer mood/energy filters.) (soundtrackflow.com)
3. Delivery & control — check scheduling, multi‑location control, explicit‑lyrics filters, offline playback and how you’ll stream to your office system (app, player device, Sonos, etc.). (soundtrackflow.com)

How to get started (practical next steps)

• If you need overhead/lobby music for everyone: trial a business music provider (Soundtrack Your Brand, PlayNetwork, Mood Media, etc.). They include licensing and ready playlists. (soundtrackflow.com)
• If you want company subscriptions for employees’ headphones or focus sessions: consider Brain.fm or Focus@Will workplace plans. (brain.fm)
• If you want fully custom, vocal‑free playlists and control: license tracks from a production library (PremiumBeat, Audio Network) and assemble a playlist under the correct commercial licence. (premiumbeat.com)

If you want, I can:

• Suggest specific “focus” or “ambient” playlist names on one of these services (Soundtrack, PlayNetwork, Brain.fm or Focus@Will), or
• Compare pricing/features for 2–3 providers (e.g., Soundtrack vs. PlayNetwork vs. Epidemic Sound In‑Store) and cite current plans.

Which of those would you like me to pull pricing/playlist examples for?
