Distributor comparison
ONCE vs TuneCore
for AI music
TuneCore's per-song annual fees compound fast on a real catalog. ONCE is a flat $2 (AI) or $1 (human), paid once, and the track stays live forever.
Disclosure: We're ONCE. We built one of the two distributors in this comparison. Every number on this page comes from TuneCore's own pricing page as of May 2026. If anything's stale, email us and we'll fix it.

Catalog migration
Switch from TuneCore in one afternoon
ONCE has a built-in migration wizard, so moving your catalog is not a track-by-track re-upload.
- Import your whole catalog from a Spotify artist link
- Keep your ISRCs and original release dates, so streaming history carries over
- Follow the guided takedown checklist for a clean handoff
Where ONCE wins
- Pay once: $2 for AI, $1 for human. No annual per-song renewals.
- Stop paying ONCE? Your tracks stay live. Let TuneCore renewals lapse on the standard plans? Tracks come down.
- ONCE is the ethical AI distributor: the extra dollar on every AI release routes to the Artist Compensation Fund. TuneCore charges AI and human releases the same and routes none of it back.
- AI provenance scanning and AI disclosure metadata are automatic on ONCE.
- ONCE's MCP server lets AI agents distribute tracks programmatically. TuneCore has no comparable agent surface.
- ONCE's pricing is the same whether you release 1 track or 1,000.
When TuneCore is still the right call
- You want TuneCore's bundled publishing administration in one product.
- You release infrequently and prefer the legacy-brand feel.
- You need specific TuneCore-only services like their YouTube Sound Recording Revenue collection.
Verdict
For AI music distribution in 2026, ONCE wins on cost (decisively), on AI policy compliance, and on agent support. TuneCore's edge is their publishing administration service, which is a real product - but it's separate from the distribution math. If you need both, run TuneCore Publishing for publishing rights and ONCE for distribution. You'll come out ahead on both.

Common questions
Is TuneCore better than ONCE for big catalogs?
TuneCore's per-song-per-year model compounds fast. A 50-track catalog at ~$9.99/song/year is roughly $499/year, every year. The same 50 tracks on ONCE = $50 (human) or $100 (AI), paid once. The AI rate is $1 more per release than human, and that extra dollar funds the Artist Compensation Fund. ONCE wins on cost for almost any catalog size; TuneCore's edge is the bundled publishing administration on Pro tiers, which ONCE doesn't try to replace.
Does TuneCore allow AI music?
Yes. TuneCore allows AI-generated tracks. AI disclosure metadata is the artist's responsibility - there's no automatic provenance scanning, which means as DSPs tighten AI rules, the risk of takedown sits on you. ONCE scans every upload and attaches disclosure automatically.
What about TuneCore's publishing administration?
TuneCore Publishing is a real service - they collect mechanical, performance, and other publishing royalties for a fee. ONCE doesn't bundle publishing administration. If you need it, you'd use a service like Songtrust, SoundExchange, or a PRO independently. For most independent artists distributing AI music, this isn't the deciding factor.
Can I move a catalog from TuneCore to ONCE?
Yes, with ONCE's built-in migration wizard. Paste your Spotify artist link to import your catalog, keep your ISRCs and original release dates so streaming history carries over, and follow the guided checklist to let your TuneCore renewals lapse on the tracks you move. Each migrated release costs the normal one-time fee: $1 for human tracks, $2 for AI tracks (with the extra dollar routing to the Artist Compensation Fund). ONCE tracks stay live forever after the one-time payment.
