SubmitHub vs Groover vs PlaylistGrow: Three Different Ways to Pay a Curator to Listen

Every few weeks someone asks me which is better, SubmitHub or Groover. It's the wrong question, and I say that as someone who runs a service that competes with both of them for the same budget. They're not really rival products. They're different billing structures wrapped around the same basic transaction: getting a stranger with curatorial taste to listen to your song. Once you see it that way, the decision gets a lot less about brand loyalty and a lot more about what you're actually trying to buy.

There are, broadly, three models here. Pay-per-submission, where you buy a shot at a curator's attention and the outcome stays genuinely uncertain. Pay-per-feedback, where you're guaranteed a response (not a yes, a response) inside a set window. And pay-per-placement, which is what we do at PlaylistGrow, where the thing you're buying is the actual playlist add, not the attempt at one.

Each has a real strength. Each has a failure mode nobody selling it likes to lead with. I'll try to be straight about ours too, since that's the only way a comparison like this is worth reading.

SubmitHub: you're buying a guaranteed listen

SubmitHub has been around since 2015, built by Jason Grishkoff, a former indie blogger, and it's probably the most recognized name in this corner of the industry for a reason. It connects artists with a network of 1,700+ vetted Spotify playlisters, music bloggers, and influencers through a credit-based submission system, and more than a million artists, publicists, and labels have run tracks through it at this point.

The pricing is transparent, and I'll give them credit for that. Premium credits run roughly $1 to $3 per submission depending on the curator, and they guarantee a response within 48 hours along with written feedback if your track gets declined. What's less often repeated is the acceptance math underneath that guarantee. The platform-wide average approval rate for premium submissions hovers around 5 to 8 percent, a figure SubmitHub itself has confirmed in past blog posts. Run the credit cost against that acceptance rate and you land somewhere between $14 and $40 per actual placement, depending on which estimate you trust and how disciplined you are about targeting curators who actually fit your genre.

One thing SubmitHub does better than most of its rivals: curator profile transparency. Every curator card shows separate accept, decline, and unreviewed percentages instead of one blended number, so you can see how a curator handles incoming tracks before you spend a credit on them. That's genuinely useful if you're willing to do the homework yourself, curator by curator.

Groover: you're buying a guaranteed reply

Groover, founded in Paris, flips the emphasis. Instead of selling you a shot at acceptance, it sells you a guaranteed human response. What Groover actually guarantees is a reply within seven days or your credits back. It does not guarantee a playlist placement, a press feature, streams, or any financial return, no matter how the marketing copy reads at a glance.

The currency is called Grooviz. Groover lists one Grooviz at roughly a euro, with most contacts costing around two Grooviz (about $2.15) and top-tier curators running higher. The refund mechanic is the real product here, and it works: Groover reports a curator response rate above 96 percent. Compare that to cold-emailing curators with no platform behind you, where plenty of artists never hear back at all, and the refund guarantee starts to look like the actual thing you're paying for. That gap between "silence" and "an answer, good or bad" is worth something on its own if you've ever cold-pitched a curator list yourself. We've written before about why free submission routes end up costing you in hours instead of dollars, and this is part of why.

Where Groover tends to disappoint artists is the same place SubmitHub does: hope creeping in where the guarantee doesn't actually reach. Guaranteed feedback is not guaranteed placement, and acceptance estimates vary by who's counting. One review put the real acceptance rate, as distinct from the reply rate, at 20 to 30 percent by our read of the available numbers, while a direct comparison against SubmitHub put it lower, closer to 15 to 20 percent. Geography matters too. Groover's bench is strongest in Europe, with 3,000+ curators, labels, radio contacts, and managers, so US-focused, Spotify-only artists sometimes find the pool thinner than they expected. We went looking for the Reddit consensus on Groover ourselves and didn't find one, which tells you something about how split the opinions actually are.

PlaylistGrow: you're buying the placement itself

We built this differently on purpose, and it's fair to say upfront what that choice costs us as much as what it buys artists. We don't sell submission credits or guaranteed responses. A campaign is scoped around a number of actual playlist placements, and that's the deliverable. Not an attempt at one.

Since 2019 we've run 2,226 campaigns for 2,002 distinct artists, resulting in 13,105 playlist placements, 5,522 of which are currently active. That works out to just under six placements per campaign on average, though individual campaigns vary a lot by genre and budget. Our busiest genres have consistently been Rap/Hip-Hop, Afrobeats, Pop, R&B/Soul and Dance/House, which tells you roughly where our curator relationships run deepest after seven years of doing this. Part of why that works, in my experience, is that a smaller curator with real taste in your genre often does more for a track than a huge generic list ever will. We've made that argument in detail elsewhere on the blog, and it's the whole philosophy behind how we build campaigns.

Here's the honest failure mode, and I'd rather say it plainly than have an artist find out the hard way. If what you actually want is a curator's written opinion on your mix, your hook, your sequencing, a placement-based model is the wrong tool. We're not built to deliver A&R-style commentary on every submission the way Groover's feedback guarantee is designed to. If a songwriter wants that kind of track-by-track critique as the main goal, not a nice-to-have, they should look at Groover or SubmitHub's premium tier, not us. We exist for the artist whose main question is "will this song land on real, active playlists," not "what do curators think of this bridge."

Cost per actual placement, compared

Model	What you pay for	Typical unit cost	Est. cost per placement	If the curator says no
SubmitHub	A guaranteed listen/response (pay-per-submission)	$1-3 per premium credit	~$14-40	Credit is spent either way; you get a response, not a refund
Groover	Guaranteed written feedback within 7 days (pay-per-feedback)	~2 Grooviz ($2.15) per contact	~$13	Credit refunded automatically if they miss the window
PlaylistGrow	Actual playlist placements (pay-per-placement)	Scoped per campaign, see pricing	Baked into the campaign, not a per-shot gamble	Not applicable; the deliverable is the placement itself

That SubmitHub-versus-Groover gap narrows a lot once you price per outcome instead of per credit. One direct comparison called the price-per-submission difference between the two "a myth" once you account for differing acceptance rates, and I think that's fair. The sticker price per credit is a weak signal. Cost per real placement is the only number worth arguing about.

Who each model actually favors

SubmitHub rewards artists who enjoy the game itself: filtering curator stats, A/B testing pitches, treating the whole thing as a numbers exercise across a pool of 20,000+ contacts. If you like spreadsheets and have the patience to buy credits in small batches while you learn which curators convert for your genre, it's an efficient tool.

Groover rewards artists who want more than a yes or no, particularly ones targeting Europe, radio, sync, or label attention rather than pure Spotify playlist volume. The guaranteed response is a real product. If your main goal this release cycle is understanding how your music reads to industry ears, not just whether it lands on a playlist, that guarantee earns its price.

Placement-based campaigns favor artists who've already done the feedback loop, or don't need it this cycle, and now want distribution handled for them. It's also a better fit if you're releasing on a schedule and want promotion running while you focus on the next song. If you're building out a release calendar anyway, our free 90-day release checklist pairs fine with any of these three models, since timing your submissions right matters no matter which platform you use. It also matters for older songs sitting in your catalog that never got pitched the first time around.

The decision rule

Pick SubmitHub if you want to run your own curator outreach at scale, you're comfortable with a low acceptance rate in exchange for volume, and you value transparent accept/decline data enough to do the filtering yourself.

Pick Groover if guaranteed, substantive feedback matters to you as much as the placement itself, especially if you're targeting European curators, radio, or label contacts rather than Spotify playlists alone.

Pick a placement-based service like PlaylistGrow if your priority this release is actual playlist adds delivered as an outcome, not a submission process you manage yourself, and you don't need curator commentary as the thing you're paying for.

None of these three is lying to you about what they do, as far as I can tell. They're selling different things wearing similar-looking websites. Buy the one that matches what you actually need from this release, not the one with the loudest ad in your feed this month.
