Kanye also claimed that streaming platforms will continue to grow in the coming years.

He tweeted: ''Two years ago we had 50 million people subscribed to music streaming services around the world. Today we have 400 million. 8 x growth. By the end of this year we will have 460 million. By the end of the decade we'll have 2 billion as projected by J.P. Morgan, Goldman Sachs etc. (sic)''

Meanwhile, Kanye was recently forced by Twitter to remove a post featuring the phone number of Randall Lane, Forbes' Chief Content Officer.

The rapper also slammed Universal Music, saying the record label wouldn't tell him how much his masters would cost to purchase.

He wrote in a series of tweets: ''UNIVERSAL WONT TELL ME WHAT MY MASTERS COST BECAUSE THEY KNOW I CAN AFFORD TO BUY THEM ... Everyone please cover me in prayer ...

''I AM ONE OF THE MOST FAMOUS PEOPLE ON THE PLANET AND UNIVERSAL WONT TELL ME WHAT MY MASTERS COST BECAUSE THEY KNOW I CAN AFFORD THEM ... BLACK MASTERS MATTER (sic)''
