It's taken from 'Muney Lane Muzik 2,' a full-length release which is set to be released later in the summer.
Mill performed "Stay Woke" in a hoodie with images of XXXTentacion and Jimmy Wopo on it.
Wopo's manager confirmed the news on Facebook.
The buzzing artist's single got a boost when people accused Kendrick Lamar of biting its sound. Now Wopo offers part two to set the record straight.
