Alexander Mack is consistent, but not repetitive. He just dropped a new single properly titled "On My Job." Mack's sound has always been refreshing, and his newest offering is no different. "On My Job" carries a strong theme of determination and perseverance through its three minutes. The self-produced track is noticeably more bouncy than his other singles and, in keeping with the theme, has a more focused subject matter. It's the third single from his upcoming album and it tells us exactly what we need to know: Virginia-based rapper Alexander Mack has "been working." Check out "On My Job" up above.
