Kanye West disses Macklemore, Taylor Swift on Twitter

Kanye West is at it again.

The rapper started Twitter beef once more, and this time, the feud was with a music producer named Bob Ezrin, who is known for his work with Kiss, Pink Floyd and Phish. West also dissed Macklemore and Taylor Swift in the process.

Ezrin wrote a scathing blog post about West, saying, "I feel like opening with 'What kind of crazy, f***ed up world is it where this guy is considered to be culturally important!!???' ... Kanye's greatest achievements have been in the form of excessive behavior, egomaniacal tantrums and tasteless grandstanding." Ezrin admitted he has not listened to West's new album "The Life of Pablo" yet.

West was not pleased.

He went on a Twitter rant, first asking his followers, "Has anybody ever heard of Bob Ezrin???" Then he followed the question with, "What the f*** does he know about rap...I'm tired of old people that have no connection with anything trying to comment on music! Do something relevant... Please don't speak on me bro ever again!!!"

And though the rapper promised in January that he would "never speak on kids again" after he apologized for talking about ex Amber Rose's child with Wiz Khalifa, he couldn't help but bring up Ezrin's kids.

"Your kids are ashamed of their dad... Sorry for speaking about kids... but could you imagine if you were Bob Ezrin's kids... I'm so sorry for them... I will send them free Yeezys to make up for the embarrassment that you have caused your family," he said. Ezrin's granddaughter tweeted that she would also like Yeezys; Ezrin retweeted her saying, "Get those yeezys granddaughter."

Then, West countered Ezrin's statement that Macklemore was a more impactful artist and said, "Bro you said Macklemore was more important musically than me... no offense to Macklemore, he's a nice human being!"

Of course, it wouldn't be a true Yeezy rant without a Taylor Swift dig, and though he didn't name-check her, he clearly made a reference to the singer when he said, "I made Dark Fantasy and Watch the Throne in one year and wasn't nominated for either and you know who has 2 albums of the year." Yes, we do know -- that's Swift who has two Albums of the Year.
