In Jamaican Patois “yiy” means “eye”. The phrase “yiy just changed” essentially means that you just got some sleep. Drake is saying that he woke up to the girl ringing his doorbell.
However, the phrase can also mean a change in mood.

That was made around the same time as ‘Work.’ There was just a time period where I was really on my island vibes. I just knew that it would be a special beat. I didn’t personally sample Beenie Man for the beat, but there’s a Beenie Man sample in the song. The beat was original with no sample in it, but the song had the little Beenie Man cut in there.

I was in the studio a lot with Drake at that time. Views is a really dope album because he went out of his comfort zone and tried something new. And basically introduced a new sound into the game with the Afrobeats and the dancehall vibes. It was something fresh.

My mentality is to always evolve, move on and never be complacent. I always want to try something else, experiment, push the envelope with my production. Some of my favorite producers—like Pharrell, like Timbaland, like Dr. Dre—were never afraid to step outside of the box and do something unexpected. I like to take pages out of their books and apply it to myself. I want to be great like they are. I want to be at the level that they’re on with their production.

[Mine and Drake’s relationship] has been the exact same. He’s just a great guy and he hasn’t changed since I’ve known him. I really appreciate that man. He changed my life, he changed my family’s life. I can’t sing nothing but praises for Drake, man. He’s just a stand-up guy and has changed the lives of many people around him.

The secret [to Drake’s success]? Bugs Bunny’s Space Jam water [laughs]. There’s no secret, it’s just love and passion for music.

According to Songfacts, Beenie Man explained to Billboard magazine how he end up on the song:

They reached out to me to clear the sample then he reached out to me to do an intro (sic) for the song It’s a big deal. For somebody to take a song that I’ve been done for 15 years, to release and put it out – it’s a big deal. It’s always great. For him to idolize me like that, it’s a big deal. [Laughs]

Drake also declared:

I am into any dancehall, any reggae, conscious, whatever, it doesn’t matter I’ll listen to anything. I feel like the writing, the melodies and the layering of the music in the genre is incredible.
