Bands recreate their songs on stage. They play their instruments and sing the lyrics. It would be te equivalent of skrillex remaking his songs in real tame, somethin that would not be physically possible and I'm not knocking him for not doing. Regardless pressing play still isn't exactly work. It'd be the equivalent of a band tracking every instrument and voice and just pretending to play, something that tends to piss people off when it does happen.
Electronica artists recreate their songs on stage, too. It's not just a 2-track that they press play on. Stems and tracks are triggered via MIDI controllers (like the Novation Launchpad in that Madeon video), and are sent to appropriate FX busses when the time is right. Doing this wrong would be the equivalent of a guitarist starting the chorus half a bar too late and throwing the song. Electronic artists "remake" their songs on stage in the sense that they play the right parts at the right time. It's not physically impossible, but it is basically just pushing buttons. Then again, drumming is just hitting things, so it's pointless to trivialize the instruments used for a live show, whether it be an acoustic instrument or a less conventional electronic one.
