I dont listen to the kids music, but i still respect him greatly. Hes 17 and look at all hes done! And i do respect that his songs are written by him, and he ACTUALLY sings at his concerts. And outside of the rock community, and excluding Lady Gaga, how many artists actually can say they do that?
And as for Duff, he respects the kid for what hes done. So what? Just because hes a rocker, doesnt mean he listens to just RNFR.
