I always thought his music had an interesting sound and his videos were always interesting as well, but I'm not sure I could get into it on a daily basis and have it rotating in my car a lot- where I usually listen to music. He seems like a really intelligent guy who is, like Megan said, trying to push people's buttons and make them think what they will stereotypically think despite the fact that in almost every interview and whatnot he seems pretty decent, even if really odd. His artwork is very cool, too.
I think it's sad that some kids try to imitate him and sometimes take his actions as serious, when it comes across more as irony a lot to me. But I don't know really.
