I think youtube knew these losses were coming well in advance.
If you create music that is commercially available you should belong to one of 3, if not all, US music publisher administrators; BMI, ASCAP, HarryFox.
I belong to all 3 but use Harry Fox to administer our rights.
Youtube has entered into an agreement with music publishers as of this year. They are paying 15% net of ad royalties.
