Yes, you may be a leading producer, but somebody has to follow behind you and whisper in your ear that you’re still mortal. (Err, classical references on Supajam?) When Mark Ronson was working in the studio with Lady Gaga, he started singing, and the Bad Romance star turned to him and went “take some lessons”. Now, she probably did this in a friendly, constructive way, but we love the idea she just cut him down. Either way, he promptly took weekly lessons, so at least he’s open to criticism. Unfortunately, this means we're going to hear it.
