For a long time, copyright collective management organisations have adapted to changes in the music world, while remaining faithful to the cooperative, non-profit, rights holder-controlled model established over a hundred years ago for example by Sacem in France, ASCAP in the USA and SGAE in Spain. Is this stability now being called into question? Does the transformation of the US giant BMI into a for-profit commercial enterprise backed by a financial fund give critical mass to this "commercial" rights management sector, hitherto limited to interstitial players, be they historical or start-ups? Can the dominant model be overturned? What assets can traditional players count on?
