Who can revive good songwriting?

The babyboomer generation brought about the amazing, socially conscious, and still popular songwriting of Bob Dylan, John Lennon, and Neil Young. Now, with another seemingly endless war at hand, who has the insight, intellect, and charisma to revive the socially conscious and still popular song? Popular music now is all -and-bling hip hop without any social consciousness whatsoever - who can we count on to have a catchy, popular melody and lyrics that really make you feel something and convey ideas that you've never had before?
