Believe and TuneCore went from blocking Suno to distributing it in just over four months

On 8 Sep 2026 Suno announced a global partnership with Believe and its self-release platform TuneCore. Tracks made with Suno's new "industry partner model" become eligible for distribution through both, and participating Believe and TuneCore repertoire will go into the new models Suno is building with the industry. Suno CEO Mikey Shulman's post acknowledges that earlier in the year the two companies had refused to distribute music from models that didn't meet their standards, Suno's included.

That understates it. Just over four months earlier, Believe was the distributor making the loudest case against Suno.

What did Believe say in April?

On 30 Apr 2026 Believe CEO Denis Ladegaillerie told Music Business Worldwide that Believe and TuneCore would automatically block distribution of AI tracks made partly or fully on unlicensed "pirate studios", and named Suno among them. He said Believe's detection had become "99% reliable" at identifying the specific model or platform behind a track. He argued that content made on Suno's already-trained models was illegal and would stay that way for the foreseeable future, and he warned that distributors who didn't act were sitting on "a litigation time bomb".

Believe signed licensing deals with ElevenLabs and Udio in the same announcement. Ladegaillerie also admitted the policy had cost TuneCore some goodwill on DIY artist forums.

What exactly changed on 8 September?

Less than the headline suggests. According to MBW's report on the deal, the partnership covers only output from Suno's new model. Tracks made on Suno's existing models are not covered, and Suno has said those models will be retired when the new ones launch. A day later Suno released v6, which it says was developed with Warner Music, BMG and Believe.

The deal also comes with controls. Suno says its watermarking and fingerprinting, built to identify Suno songs off-platform, will apply to music distributed through Believe and TuneCore. Its new download limits, which MBW reports took effect on 3 Sep (20 downloads a month on Pro, 60 on Premier, none on Suno Studio), are meant to stop mass uploading to streaming services.

So Believe's stated position on the old models hasn't moved. What moved is that there is now a Suno model it has a licence for. Suno, meanwhile, is still fighting the industry in court. Per MBW, UMG and Sony are still suing it in federal court in Massachusetts. The Munich Regional Court ruled against it in GEMA's case on 31 Jul, a ruling that is not yet final. SOCAN filed a claim in Canada on 2 Sep, and four musicians filed a proposed class action over the use of their names and voices on 31 Aug.

What does this mean for artists?

There are two groups of artists here, and they get different deals.

Artists whose music is in Believe's catalogue get a consent process, at least on paper. Ladegaillerie told MBW in a September interview, cited in its October report on Believe's Spotify deal, that artists first opt in to AI programmes in general and are then offered each opportunity separately, naming Spotify, YouTube and Suno, with the right to decline any of them. That is better than the scrape-first approach that got Suno sued. But the terms are not public: neither Suno's announcement nor MBW's report on the deal gives royalty rates or financial terms. When we checked TuneCore's AI & Data Protection Program page on 23 Oct, it listed Udio and ElevenLabs as opportunities, with no rates, and didn't mention Suno.

Artists who make music with Suno are in a stranger spot. Whether a track can be released through TuneCore now depends on which Suno model produced it, and that is checked by the distributor's own detection and Suno's watermarking. A song made on an older Suno model in August stays blocked. A similar song made on v6 in September may get through. The artist didn't sign either agreement.

What we think

Believe's detector didn't get any worse at spotting Suno between April and September. A track it flagged as "pirate" can now be flagged as "partner" with the same certainty. Detection was never only a protection tool. It was what gave Believe leverage: a credible threat to cut off one of the biggest AI music platforms from a major distribution route until it came to the table. As Zinstrel noted, the open question is whether Believe is confident in Suno's new licensing or simply found it impractical to keep blocking a company that big.

We think the more lasting effect is structural. Distributors now act as licensing gatekeepers for AI output, not just as pipes to streaming services. That gives them a new revenue line (licensing their catalogue for training) and a new kind of power: the ability to decide which tools their uploaders may use. The winners so far are Believe, which ends the forum backlash and gets a seat inside Suno's model development, and Suno, which gets distribution legitimacy while its lawsuits continue. Rights holders who opt in may also benefit, if the money turns out to be real.

The people with the least say are DIY creators. Their tracks are scanned against rules set in private negotiations, and those rules can reverse within months. Believe says its approach rests on four principles: consent, control, compensation and transparency. In our view, transparency should extend to uploaders too. That would mean a public, dated list of which AI models TuneCore accepts, notice when that list changes, and a real appeal route when the detector gets it wrong. Even at Believe's own claimed 99% reliability, a detector applied at that scale will get some tracks wrong, and each of those is somebody's release.

Until that exists, our advice is practical. Keep a record of which tool and model version made each part of a track, check your distributor's AI policy before you upload, and don't build a release plan on an AI tool your distributor hasn't publicly licensed.
