I would think “God’s Plan” would show up, then, because it’s a worldwide smash. I’m especially surprised
SharksFan99 never hears it considering how incessantly his radio station plays “Young Dumb & Broke” and Khalid is clearly influenced heavily by Drake. I even remember hearing “Young Dumb & Broke” when I was driving with my friend in Scotland last January; he switched off the channel immediately when it came on. I was with him, by the way, during the week “God’s Plan” was brand new.
I've only heard "God's Plan" once or twice on the radio before . It's "Freaky Friday" that I have never heard being played on the radio, despite the fact that it is at #4 on our chart. As for "Young Dumb & Broke", thankfully the Top-40 radio stations in my local area have stopped playing the song, which is a relief, because like your friend who lives in Scotland, I was starting to get sick of hearing it so often.
