I'd call heavily reduced costs of distribution progress. Ultimately (when the dust settles) it will mean that a greater proportion of your music dollar can go to artists who create songs and less to the intermediaries. Really, the idea that someone can write, produce and perform a song, upload and market it themselves and then either sell it to people across the globe or make money off extras (ie concerts, merchandise, etc) is unbelievably cool compared with what had to happen in the past.
