Concept demo Three prepared tracks. Uploads are not available.
Your song, read by an AI that listens.
Hear what a producer hears, pinned to the second. Choose one change, see exactly what it protects, and take the instruction to the tool you already use.

Prepared answers. Nothing is sent.Answers cover structure, weak spots, the hook, the changes, the mix and instruments, and the measured numbers. Anything else gets a reason, not a guess.
Suggested changes
Three, most important first. Each says what was heard, what moves, and what stays. One is applied for real so you can hear it.

About the concept
Why now
Creation is solved. Suno, Udio and ElevenLabs will make you a song in a minute, and now they edit it too. Deciding what to change, and what to protect while you do, is not solved. SongLLM is the critic for that step, not another editor: it listens, points at the seconds, and hands a bounded change to the tool you already use.
- 2026-01-06Universal Music Group and NVIDIA extend Music Flamingo across UMG's catalog. Understanding, not generation, at label scale.
- 2026-08-13Suno Studio 2.0 ships a chat bar that edits an existing song by text. Premier tier. No public API; partners go through an intake form. The refine loop lives inside the generators now.
- 2026-09ElevenLabs music inpainting regenerates one section and keeps the rest as reference audio. The primitive for a bounded change exists. Something has to decide which section.
Where this goes
The three tracks above got the same treatment: a shape, a tempo, a key, a verdict and timecoded notes before anyone pressed play. At catalog scale that is the product.
Inside the generator
Every render gets a reading before the user hears it. Flat verse, buried hook, ending that ran out: pointed at, with a bounded change the tool can apply and a list of what it must not touch.
At the label
Ten thousand demos a month, each with a shape, a tempo, a key, a verdict and a timecoded note. A&R reads the ones the critic flagged, and hears the flag before pressing play.
In the DAW
A second opinion that listens to the bounce, not the session. Three changes in the language of the tool, each with what it protects, and an A/B at the moment it touched.
