An unlimited beat lease is an agreement between an artist and a music producer that gives the artist legal permission to make a song using the producer’s beat, but doesn’t limit the amount of streams or sales the artist can generate with their newly created song.
All beat leases, including an unlimited lease, are non-exclusive. This means ownership of the beat remains with the music producer and they can continually sell leases of that same beat to other artists until someone purchases the exclusive rights to the beat.
