Whilst the revised bill still says that all systems must inter-operate, it doesn't have to be enforced if the online music stores have the permission to use DRM from the rights holders, such as musicians and record labels.
The law could, in France at least, spark a power shift between Apple and the major labels. Until now, Apple has held the upper hand as it runs the hugely popular iTunes service, which sells all music at the same price - something which the labels do not like. But if Apple were to require permission from music labels to carry on trading under the same terms in France, that could shift the balance of power, according to industry observers.
The bill must still win approval from both houses of the French parliament. The first vote on it is expected next week.
