Unlimited leases are just that: unlimited. There are absolutely no limits on how many radio stations your song can be playing on, how many streams you can get, how many music videos you can create. Zero limits. However,
you do not own the instrumental with an Unlimited lease. I retain ownership of the instrumental. If you wish to gain full ownership of the instrumental, then an Exclusive lease is for you. In addition, with an Exclusive
lease I get 50% of publishing rights on the song as the producer, whereas with Unlimited or below I do not get publishing rights.
