Despite his professed antipathy towards DJs, Deadmau5 was fine about answering questions for his Top 100 DJs profile in past years. This year, however, through his management he demanded to know what position he was before he would do so. Because DJ Mag doesn't give out positions until all the results are announced, we didn't do this — and so he refused to answer the questions.

The Mau5 may have fallen in the rankings this year, but he still clocks in as the Highest Live Act in the chart. His 'Album Title Goes Here' album was nominated for a Grammy, but it was for his outspoken beefs with various other prominent music figures that he continued to make the most headlines this year. 
Most recently, Deadmau5 waded into a row between DJ Michael Woods and Justin Bieber after Bieber demanded that Woods play hip-hop in a Singapore nightclub. The Mau5 wrote on Twitter:  “Dear @justinbieber , would you please grow the fuck up already? In the meantime, put a shirt on, and stay away from nightclubs”.

Predictably, he received a barrage of abuse from 'Beliebers' back on Twitter. 
Deadmau5 has also allegedly been embroiled in litigation with Las Vegas high roller Don Johnson, who apparently offered Deadmau5 $200,000 one night in 2011 to play 'Living On A Prayer' by Bon Jovi during his set. The Mau5 obliged, but then Johnson — despite dancing onstage uninvited at the club when the Mau5 dropped the incongruous hair metal cut — wouldn't pay up. That saga continues.
