Last night, Drake's 4th Annual OVO Festival at Toronto's Molson Canadian Amphitheatre was an all-star celebration. Guests included a who's-who of today's biggest rap stars, from Lil Wayne to French Montana, from Big Sean to Wale, from J. Cole to Miguel

But perhaps most surprising of all, an appearance from none other than Kanye West.

Drake has sent subliminals at Kanye for the past several years. He made no secret about his ambitions for hip-hop's throne. A throne that Kanye has occupied for the past few years. So last night's news left a lot of rap heads scratching their heads. How could Kanye appear, not as a headliner, but as a surprise guest, at a Drake concert, in Drake's own city? 

What were Kanye's motives? We took a look at the various theories flying around the hip-hop world and broke them down into five distinct catagories. We then ran them through a high-tech machine that determined the exact probability that each one might be true, presented as a percentage. So allow us to break down What Kanye's Appearance at Drake's OVO Fest Really Means.
