Deadmau5 trolls DJ Tiesto on Twitter after playing Avicii's set at Ultra 2014

The Ultra Music Festival, one of the biggest music festivals in the world had a bit of drama this year. The massive celebration which took place in Miami this year, deadmau5 replacing Avicii for day 2 as the latter had to be hospitalized. The 'Strobe' DJ played a sold out set on the mainstage of Ultra.

Before going on stage, deadmau5 gave some hints on Twitter as to what he would play;

Closing the day 2 of the festival, Deadmau5 was a special guest at Ultra trolled Martin Garrix by dropping the McMaNGOS Funnymals version of popular track 'Animals'. Deadmau5 had previously poked at Garrix over said track on twitter, taking it one step further when he performed the unofficial parody of the track.

Right after this, the mau5 played a mash-up of 'Ghost N Stuff' and one of Avicii's signature tracks, 'Levels'. Whether or not this was also a slight to his fellow DJ, is not clear. However what happened next was a back on forth on Twitter with popular artist DJ Tiesto. Here is the exchange.

The highlight of @deadmau5 his set @ultra was when he played @Avicii 's levels! #amazing

@tiesto are you about to give me shit for playing levels? Christ if I had a nickle for everyone who played levels, I'd buy a 15 mil house.

@tiesto @Avicii how does one play a track sarcastically? Am I supposed to sneer while hitting the sync button? Or is that ironic?

@tiesto I played it to help funding for NASA. They're incredibly under funded. It's sad really.

DJ Tiesto also added what he thought of deadmau5 playing the parody version of 'Animals' 

Also animals by @MartinGarrix was and is an amazing epic track and he has 100 more epic releases coming in the future #supertalent
