gonna have to stay uninformed on this one. Oh wait - you said Jason, not Justin (Beiber. *gag*) Okay then.

It's possible to get Jason Mraz and The Boob, I mean Bieb confused? The Content Advisory says Bieber causes nausea and Mraz causes euphoria.

I do find some of Mraz's stuff to have a slight Mercury influence. Though I haven't heard a lot.
