Jason Mraz is a disciple of the gospel of do it now, purveyed by Dave and Dave Lite, aka John Mayer. It's a fine enabler of a message, of course, and people who like their naivete served with a hearty dose of cynicism lap it up. But this guy actually sounds happy, and that makes Jason Mraz stand out. The joy of Mraz's logophilic lyrics, delivered in a style that sounds like the sprightly bastard child of Broadway tenor and Village hipster, deliver the "don't worry/be happy/for tomorrow we go poof" philosophy with somewhat more credibility than its other promulgators. He's not as morbidly obsessed as Matthews, and seems less self-absorbed than Mayer. It may be laughable to buy the conclusion that "nothing really matters in the end" from twentysomethings, but Mraz is one "curbside prophet" who lets you laugh.
