Hi, I have an original song that has been shortlisted by a client for a possible sync licensing deal. I wrote, performed and paid for the recording in question and so own the masters. And I am self-published so the publishing is under 'Control'. I am a member of APRA so all back end royalties will be collected by them. There is a clause in the contract which seems standard enough (or not?), though I am not too sure, since it mentions "sides" something I have not heard before, thus why I wanted to get second opinion. Here is the clause: "This agreement requires you to grant a non–exclusive licence for the rights to the recording and the rights to the composition. These are also called “sides”, the master–side and publishing–side. It is a standard industry practice that this will be split 50/50 between the owners of the master and the owners of the publishing."
