Not since blast against Wiz Khalifa has Kanye West gone in on someone with such force.
This time, the target was Deadmau5, who was annoyed that Yeezy had apparently been trying to illegally download his company Xfer Records' Serum software.
The fact that Kanye came back not knowing how to pronounce his name seems strange considering they are both associated with Tidal, the music streaming service currently under much ridicule.
Unfortunately, there wasn't much back and forth between the two artists, as after Deadmau5 had gone in on Kanye's current money problems he decided to head to bed.
Could have been one of the biggest twitter beefs of 2016.
