Can music change the world?

"At the recent Royal Packages, Robert has been addressing the question “Can music change the world?”  If the current resident of 1600 Pennsylvania Ave (less than 500 metres away) was to open his bedroom window at this very second, he would hear the strains of “Easy Money” floating in. I am not sure exactly how that might inform his world view. I suspect the subtlety of the lyric and the music would be lost at that distance. And he probably finds money easy enough already. But hopefully the music will change some of those attending the concert tonight. And with them, in a small or large way, the world. There has definitely been a shift in the perception of this band during this tour."
