He makes happy, catchy music for middle-aged people to get stoked about, but I still think he's a sub-par musician.  The lyrics are uninspired--even for singing about cheeseburgers and making several songs about the exact same thing.  Then there's the music;  again, weak and mundane.  I really don't expect someone like him to be really great, but when people call him a good musician it gets to me.  And it's not that I'm not into this type of music, it's just that I think he's waaaay overrated.
