No, they must be your original compositions. We DO NOT accept compositions that you did not create under our Publishing Administration agreement because the original copyright is owned and/or controlled by another songwriter & publisher.
You can only submit original compositions, which are compositions that contain music & lyrics composed by you, the songwriter.
Be advised that submitting compositions that have co-writes are accepted. We will collect your individual share and will ask that you please provide us the names and shares of your co-writers so we can ensure proper credit and registration. Of course, your co-writers can join our service as well if they do not have a Publishing Administrator.
