David Guetta
Press play, off we go, mime all the show.
If anyone doubts this, have a look at the youtube footage showing him doing it.
I get that he's constantly busy and that he works tirelessly across the Globe and so some of his shows are live and occasionally he "has a day off" with a prerecorded show, but my god that is awful. I'm not paying for someone to press play, that's taking the piss.
For the record, I absolutely detest his music.
