Devil's advocate here: why give welfare to artists (really, the labels they sign their rights over to) when so many great pieces of art actually exist that were made by artists who died penniless? Van Gogh, Gauguin, I just don't buy the notion that extending copyrights way, way past death help the artist in any way. Why fight for labels' rights, when they largely amount to copyright trolls? Their artificial fears have made their way into YouTube, which just has to take those legal recordings down (they don't), because they're just so scared (they should not be) that this might be something that belongs to a troll. When the real musicians get their content taken down after Big Label overtly steals it, we're getting trolled.
