Real musiciansfor your AI songs.
They re-record your track, part by part — vocals, drums, bass, guitar. You own a real recording.
Hear the difference.
Press play — this is a real track split into its stems. Mute a lane, solo another. Every one of these parts can be replaced by a human.
A 100% AI song can’t be copyrighted.
One real musician fixes that.
Fully machine-generated audio sits in a copyright gray zone — there is no human author to protect. Replace even one stem with a real performance and you have authorship you can stand behind: clearer ownership, cleaner royalties, a record you actually hold the rights to.
