Stupid with a side of lazy

I do not understand the whole Drake phenomenon.

Take this song for instance. What's my name by Rhianna and Drake. (Click on the link).

While I actually do like this song for some reason, I just can't help but think that Drake sounds like the laziest, dumbest piece of stupid.

Drake, if you don't know the square root of 69, then don't rap about it. Oh, 69, haha...that's mature.

He just sounds like he showed up unprepared without anything to sing about, so he just totally wings it. And the result is less than intelligent.

And he sounds like this in every song. I do not like it. But he's rich and I'm not, so maybe I should shut up and start singing about nonsensical math problems.
