I know this is a 'troll' thread (I say that loosely because I know it is just to get a reacion out of people, saying anything is bigger and or better than the Beatles sparks an outrage (See Oasis))
Anyways, I disagree, I believe the Beatles are much better because of the simple fact that it seemed like the Beatles culd seemingly take on any genre of music (during its time) and set a bar while at it. Also, claiming that Skrillex has more 'memorable' songs or that 'most peoplke know his beats' is a complete lie.
More people hum a Beatles tune, be it Yesterday, Let It Be, Yellow Submarine, or even Lady Madonna or Eleanor Rigby. I have yet to hear someone hum a Skrillex song.
BUT - I can give it to Skrillex that he's helping to make more popular different types of Electronic music, but even then, many bands have done this (see - Oasis, Radiohead, Pink Floyd, and much, MUCH more).
TL;DR: No, Skrillex isn't bigger than the Beatles.
