BlocBoy JB has linked up with 21 Savage for “Rover 2.0.” Along with “Shoot,” the Memphis rapper’s track “Rover” gained underground buzz last year. Drake shone the mainstream limelight on the rapper after he was featured on BlocBoy’s song “Look Alive.” The song debuted at No. 6 on Billboard’s Hot 100 chart. The new version of the track finds 21 Savage delivering some hard-hitting rhymes over the piano-driven instrumental. Listen to the track below.
