What it is
SourceAudio lets labels, publishers, and creators opt catalogs into AI dataset partnerships rather than leaving music-model training entirely opaque. It is notable because it frames dataset licensing as a recurring commercial channel, with public examples of catalog scale and rights-holder revenue rather than only a generic rights-cleared claim.
