They have one of the most solid, mutually beneficial friendships in the music industry. But could the bromance between rappers Kanye West and Jay-Z be over? According to Kanye, the pair are having some disagreements about Tidal, Drake... and North and Blue Ivy's lack of playdates. As ridiculous as it may sound, the words came from the mouth of Kanye himself during one of his Seattle concerts on Wednesday night. Talking to the crowd in usual Kanye transparency (read: oversharing), he told the crowd about his woes - namely that he won't be releasing any collabs between himself and Drake because of the "streaming wars" between Tidal (which he has a stake in) and Apple.

In classic Kanye fashion, he addressed the crowd like so: "Y'all ain't get what y'all was suppose to get with me and Drake because of some Tidal/Apple [Music] bulls**t," he said at the concert. "This s**t got me tight, yo! Every time I perform ['N***as in Paris'], I think about this s**t. I think about the politics and the bulls**t. I think about how hard I go for music, for art, for y'all, the fans. How hard we go."

He then went on to describe the complicated position this places him in. Because Drake is affiliated with Apple Music and Kanye and Jay-Z are stakeholders in Tidal, it means that any collaborative efforts between them become embroiled in the larger issue of Tidal versus Apple. Kanye even explained how it's affected his relationship with Jay-Z. "It went into some Tidal/Apple political s**t about percentage on songs," he said. "I can't take this s**t, bro! Our kids have never even played together." Ouch.

His reference to Blue Ivy and North hinted at a seemingly old feud between the pair - one revolving around their wives Beyoncé and Kim Kardashian and how they don't get along. Many will recall that Beyoncé and Jay-Z didn't attend Kanye and Kim's wedding, with both women rarely making public appearances together. According to Kanye, Jay-Z called him after Kim's robbery but he felt the proper thing to do - when your wife is held up at gunpoint - is to pay your respects in person, "like brothers". He has a point. We wonder what Kim's take on the matter is?
