Pretty low effort, just some spacey instrumentals and repeating the same three note melody on top of some utterly generic lofi beat he probably bought off a dude for like $20.

Absolutely nothing but respect to him for managing to somehow spin being the clown prince of Youtube into being a sadboy emo rapper and succeeding wildly at it. Kinda like how Doja Cat went from a poster who made this to sitting at the top of the music industry.
