Yeah. I think the recording sounds a bit too good. Whoever mixed it is either an unknown prodigy or an experience sound engineer (or even engineers). This is a little higher quality than a local studio or home mix. I'm not buying his story either. He's a product.

I would go even further and question whether he wrote the songs at all, or if he did, whether he (or someone else) hired a professional song writer to arrange them. While they are simple in form, being simple is harder than most people realize. A lot of producers spend a lot of time simplifying the arrangement to make the songs they're producing more palletable to the general public.
