I love Murs, personally. And I think he's pretty talented, yet I think what makes him so appealing is his personality on the mic. He's got a great presence and is fun to listen to. Doesn't take himself very seriously, and just genuinely seems like someone you'd want to hang out with.

That said, I realize he's pretty damn talented so this isn't to say that his mic presence is the only reason he's worth listening to, I just think that it is the primary reason he's had the longevity he's had, moreso than his talent level.
