Even the people who you think don't do it sometimes change their mind, don't throw your money just yet.
k first of all, I actually enjoy Deadmau5' work as he is currently my favorite musician. I'd pay for just about anything he releases.
secondly, like I said before, I know Deadmau5 and his ethics very well. I watch his livestreams on a regular basis, I read his super long Tumblr posts, and I read everything he posts on Facebook and Twitter. you could call me a bit obsessed, but idgaf. he wouldn't do something like this just for the publicity.
