> Notoriety and because he can?

Yeah, I'm not trying to downplay what he did. More effort than he implies but still, mission accomplished.

It's just that he says his aim was:

to be a successful musician in the UK with a Top Five single in the charts

And he's talking like he achieved that, the easy way, with a "hack" no less. And it just doesn't seem to me like he's actually a successful musician yet.
