AI start-ups are rebuilding the label: SoundBreak courts Finesse2Tymes, GRAI licenses MassiveMusic

Two small AI music companies made moves this autumn that look less like software launches and more like label business. GRAI announced on 15 Oct 2026 that MassiveMusic, part of Songtradr, will supply both the catalogue for its streaming app and a dataset to train its own model. A month earlier, Zinstrel reported that SoundBreak, the AI co-writing platform, was about to add Memphis rapper Finesse2Tymes as an artist partner. Catalogue supply, training data and A&R used to be things labels did. Now AI start-ups are doing them, on their own terms.

What did GRAI and MassiveMusic agree?

Two separate agreements, according to GRAI's press release, datelined Warsaw:

• Catalogue. MassiveMusic delivers commercial repertoire through a single feed, drawing on participating independent and distributor catalogues under its existing rightsholder agreements. Approved titles go live within minutes. Rightsholders are paid and get usage reports for plays on GRAI. MassiveMusic also supplies metadata across more than 30 dimensions (mood, energy, instrumentation, key, era) for search and recommendations.
• Training. GRAI trains an in-house model on a dedicated dataset that rightsholders approved specifically for AI training through MassiveMusic's opt-in system. The release says this licence does not by itself authorise downstream creative uses of the recordings or compositions.

The app isn't live. Early builds are being tested on a MassiveMusic test catalogue, and GRAI's site offers only a waitlist. The release also says GRAI is one of the first two companies to license patents from Music IP Holdings, and that it bought Hangout, a social listening platform from the people behind Turntable.fm, in September. Zinstrel's write-up notes what wasn't disclosed: which labels or distributors are in the feed, how many rightsholders opted into training, and a launch date.

What is SoundBreak doing with a rapper?

SoundBreak launched in February. Users co-write songs with AI models of participating songwriters, each trained, with the writer's participation, on their songwriting style, as Music Ally described it at launch. Kevin Griffin of Better Than Ezra is a co-founder and one of the AI co-writers. Zinstrel notes the roster has leaned indie, pop and rock, with no marquee rap artist until now.

On 9 Sep, Zinstrel reported, citing Griffin, that SoundBreak was set to announce Finesse2Tymes, with an open call for beats while he works on a new album. Finesse2Tymes (Ricky Hampton) had a Hot 100 entry in 2022 with "Back End", which peaked at 86. No deal terms were reported, and we could not find a public announcement from SoundBreak or the artist. Treat it as reported, not confirmed.

SoundBreak's money model is what makes this label-like. Its site advertises a 50/25/25 royalty split on tracks distributed to streaming services, with $9 and $29 monthly paid tiers. Zinstrel's April feature describes the paid-tier split as 50% to the user who made the song, 25% to the artist whose model was used and 25% to SoundBreak. And on 7 Oct, per Zinstrel, SoundBreak emailed users asking whether they would use a marketplace to license songs made on the platform for videos, ads and podcasts, paid from subscription revenue. No split for the marketplace was given, and SoundBreak said the plan was still being shaped.

What it means for artists

Start with who says yes. In GRAI's deal, the opt-in for training belongs to the rightsholder. MassiveMusic's own page for AI training data talks about tracks approved by the rights holder and says creators get "protection and compensation", but it doesn't describe artist-level consent or how training payments flow. Neither does the GRAI release. For a signed artist, the rightsholder is the label. For a self-released artist, it may be a distributor or aggregator, depending on what you signed.

So the question to ask, if your music reaches services through an independent distributor, is a plain one: does my distributor have an agreement with MassiveMusic or a similar supplier, and has it opted any of my catalogue into AI training? We have not seen evidence that any particular distributor has done this. But nothing in the public material says the artist would be asked separately, and that is the gap.

Finesse2Tymes is a useful case for the SoundBreak side. In May he posted videos of himself running his record contract through ChatGPT, called the deal one-sided and said he had found out he doesn't own his masters. Complex reports his deal is with Mob Ties, J. Prince Jr.'s label. An artist in that position licensing his style to an AI co-writing platform raises real questions: what the model is trained on, who controls it if the label relationship changes, and whether the 25% artist share is his alone. Zinstrel's April feature says artists who own their masters can add unreleased recordings to fine-tune their model. That is a perk that depends on owning your masters.

For producers, the beat call is the practical part. If you submit, read the terms for who owns the beat, whether it can train anything, and how you get credit if a fan-made song built on it gets distributed. We looked for producer reactions to the beat call and found none we could verify, so we aren't reporting any.

What we think

The interesting thing isn't that AI companies want catalogues. It's that they are splitting the label's old bundle of jobs and rebuilding each one as a licence. GRAI gets supply and training data from a B2B intermediary instead of signing anyone. SoundBreak gets "artists" by licensing their style and splits revenue with fans who prompt the songs. Neither needs a traditional A&R team or a 360 deal.

That can be good for artists. GRAI's two-agreement structure is the right shape: separating "stream my music" from "train on my music" lets a rightsholder say yes to one and no to the other, and the release says training doesn't cover downstream uses. SoundBreak's 25% artist share is at least a published number.

But consent has moved one step further from the artist, not closer. The yes now sits with whoever holds the rights in an intermediary's system, and for most working musicians that's a label or distributor they signed with before AI training was on the table. The winners are the intermediaries, MassiveMusic first, which become toll booths for training data. The losers are artists who don't own their masters and won't be asked. We'd like every AI-licensing intermediary to publish two things: whether individual artists can opt out, and what a track earns from training, separate from plays. Until then, "opt-in" describes a contract between companies, not a choice made by the person who wrote the song.
