What MBD is saying is a shtus. There was never money in albums. The point of the album is name recognition, so you get paid more for weddings and concerts. MBD already has the name recognition so he has less of a reason to put out albums, and the fact that there is pirating makes him even less motivated. But it isn’t to blame.
Anyway. This is the beauty of capitalism, that any Tom, Dick, or Harry can release a single. That is a good thing. It forces the good to do even better. And we don’t need a filter, the consumers will be the filter.
