Hi, I own the masters of my sound recordings. These have already been released commercially via several albums via my label. Another label now wants to release some of the songs as a compilation/ and for want of a better word, best of album. The deal is exclusive to them for this release only. They have the right to sell the album as they see fit, and once they recoup their costs, I will receive a 50/50 cut from sales. My question is, it is a simple contract and fairly straight forward. But there is no mention of copyright of master recordings in contract, so wanted to see, does this need to be specified in writing or since I've already outlined the ownership of sound recordings are mine, it is not needed? I do plan to add on CD label (around the edges) the usual 'sound recordings owned by (insert name) (p) and (c) 2015. Does this suffice under Intellectual Property Law?
