Kanye West's Rant Wasn't About Drake

Kanye West's onstage rant about other rappers copying his style -- from his sound to his stage -- wasn't about anyone in particular ... even though there were indications it could have targeted Drake.

Sources close to Kanye tell TMZ the rapper's Edmonton outburst this weekend was just 'Ye being 'Ye ... the call-out was to all the younger guys coming up in the rap world who Kanye feels rip him off on the reg.

We're told none of the speech was about Drake -- in fact, our sources say 'Ye's got nothing but respect for him -- and there's still talk about them doing music together.

So, what seemed like an angry rant was really just Kanye pumping up the crowd, we're told. He should be happy, anyway ... his 'Father Stretch My Hands' just hit #1 on Urban Radio.
