The EU's required automated copyright censorship regime would do nothing to pay artists more (and not much even to pay publishers more, not that we should care). The effective way to pay artists more is with a mandatory payment to the artist for commercial redistribution.

The law would need to be carefully designed so that the publishers could not take these payments away from the artists through some nasty contracts. It should be a crime for the publisher to ask how much of these payments some artist receives.
