Scoring multiple viral hit singles is most young rap artists’ dream, but doing so while still in high school takes that flex to a whole other level. That’s precisely what happened with Lil Mosey, the Seattle-area high schooler whose part-sung, part-spat tracks “Noticed” and “Pull Up” put him in a national spotlight. Both made it onto 2018’s Northsbest alongside a number of similarly executed tracks, which provided a snapshot of the teen’s approach. Those who found themselves uncontrollably bopping to that album won’t be taken aback by Certified Hitmaker. This follow-up sticks largely to the model of its predecessor, fixated on girls and the hustle on “Dreamin” and “Kari’s World.” Guests like Gunna and Trippie Redd serve as suitable foils to Mosey’s comparatively poppy style, bringing their signature flows to “Stuck in a Dream” and “Never Scared,” respectively.
