I'm not a huge Ben Harper fan by any means at all - in fact, I don't own one CD and I don't believe any of his songs are on my iTunes. But I did happen to run into him as I was getting luggage at baggage claim in Dallas a few years ago. He was standing off by himself waiting for his stuff to show up and I recognized him. I walked up and just said that I enjoyed his music (which was partially true - I liked one song at the time) and that I wanted to wish him luck on his current tour. He offered up his hand, shook mine, and then engaged me in a five minute conversation about my own life. I thought that was really cool that he actually cared what I did for a living. He seemed really appreciative that I took the time to wish him luck on his career. So from my own little five minute experience, I don't think Ben Harper is a douche.
