"What do you mean by @JustinBieber was my favorite song of 2015," West wrote Sunday on Twitter.
"What Do You Mean?" also broke music streaming service Spotify's record for a single's first week streams globally as it was played more than 21 million times in five days.

West's comment on the song followed an earlier declaration on Twitter from the outspoken rapper that he is planning on releasing multiple Yeezy fashion collections and albums later this year. "No more fashion calendar... I'm going Mad Max... 6 collections a year...3 albums a year," he wrote.
