any song, any stage.
We test music –
not how you made it.
See how people respond before investing more into production.
Test the version you’re working on before another round of changes.
Get a private signal before release or promotion.
See how people respond outside platform algorithms.
Let people react to the music before the production method becomes part of the conversation.
Same test. Same conditions. Same question.
Let them hear the song before they judge the story around it.
Before hearing a note, people can already be influenced by “AI”, follower, count, streams, popularity, likes, and comments.
We remove those signals from the first response.
Posting tells you if an algorithm showed it. We tell you what happened after a real person heard it.

Our listeners are compensated for:
They do not earn more for saying YES.
They do not lose money for saying NO.
YES and NO pay exactly the same.
Paid listening sessions must pass our verification process before the responses are accepted.
If a listening session fails verification, it doesn’t count toward your listens.
Rejected responses are validated

At least 30 seconds before Carr asks for the initial response.
No. YES means:
“After hearing the first 30 seconds, I would choose to keep listening.”
Yes. Carr can test demos, works in progress, rough mixes, finished songs
and released tracks.
Yes. Carr can accept AI-generated, AI-assisted, hybrid and traditionally produced music. The production method does not determine eligibility.
Not before the initial listening decision.
Carr’s first test is about the listener’s response to the music itself.
No. A Carr Private Test is not a public music release.
Carr does not provide listeners with a download button. As with any digital playback service, we don’t claim that unauthorized copying is technologically impossible.
Yes. Submitting a track for testing does not transfer ownership to Carr. Carr only needs the limited rights necessary to privately stream the track as part of the test.
No.
Its responses are removed and replaced.
Your test is not complete until Carr has collected 25 valid verified listens.
No. That’s not what Carr is designed to do. We show you how this group of listeners responded. You decide what the result means.
