Examples of Singing: "Roll Up," "Young, Wild & Free"
Wiz likes to drop catchy melodies in his songs. "Young, Wild & Free" is a prime example, showcasing his versatility, tight bar, and weed references simultaneously. Dude was crooning all over mixtapes before he blew up and kept the trend going on some of his first major singles like "Roll Up" and "No Sleep."
Conclusion: Wiz's signature flow will always be a mix of both styles of delivery.
