Last night, Kanye West tweeted a photo of a computer monitor with the main window set to the YouTube audio for Sufjan Stevens' "Death with Dignity." However, there was also a tab open pointing to the notorious file-sharing site the Pirate Bay, as well as one that seemed to indicate that the synthesizer plugin Serum was being illegally downloaded. Serum is sold by Xfer Records, which was co-founded by Deadmau5. Last night, Deadmau5 took notice, tweeting "What the fuck @kanyewest ... Can't afford serum? Dick. Let's start a Kickstarter to help @kanyewest afford a copy of Serum. He needs a small loan of 200$ #prayforyeezy." Update (2:36 p.m.): Kanye's camp has confirmed to Pitchfork that the laptop in question is not Kanye's. He posted the tweet as a joke, referring to the rampant piracy of The Life of Pablo. Update (6:22 p.m.): Deadmau5 has responded to West's tweets.

Now, Kanye has fired back with a series of tweets. Read them below.

Both Kanye and Deadmau5 are founding co-owners of TIDAL. That photo above is from the TIDAL launch.

CORRECTION: A previous version of this story said Kanye had tweeted out a photo of a Samsung computer. In fact, the photo shows an Apple laptop hooked up to a Samsung monitor.
