Well my thought was to use the contract at the back of "The Craft And Business Of Making Music" which states that I own I rights but that I'll give them 1% of the Master Use Fee that's paid to me, NOT the SYNC FEE (which is where A lot of profits are as I understand it because this is paid on reruns and the master use fee isn't).
To give people 1% of the total profits might be a much bigger amount.
So I'm still inclined to go with the 1% of the Master use fee, this would at most be 10% (on some songs with alot of players) and I'm hoping that's a percentage that wouldn't cut into a publishers profit, I mean they typically wouldn't take 100% of the master use fee would they?
