As Ars Technica reports, the Open Rights Group has published an estimate how revenue -- created if musical copyright in the EU would be extended by another 45 years -- is going to be distributed:

Only the labels and the top performers would benefit, while the great majority of musicians would little -- less then € 30 -- or nothing at all. This makes it abundantly clear that the main argument for the extension of the terms, helping aging musicians, is utterly insincere. Yet another indication that the expansion of copyright does not benefit creators, but amounts to a subsidy of the exploiters. (see also Berndt Hugenholtz on the subject, or more generally, Martin Kretschmer's work on IP based incomes of creative producers.)
