His team are just releasing pre recorded songs.
Singers and rappers usually pre record a bunch of songs in case smth like this happens, and yk how some of Juices newer songs have an animated mv?
Well the reason it takes a while for a new pre recorded song to come out is bc the only thing they have is him singing. His team need to edit and work w the recording as they would if Juice was still alive, if you get what I mean.
