2 Chainz never stops working, even on his birthday. For his 38th (which he celebrated yesterday), the ever-present Tity 2 Necklace has come through with a motivational anthem, “No Off Dayz”. It might not immediately replace “Birthday Song,” as the Chainz song people throw on for their born day, but if you’re a workaholic like the Atlanta rapper, you’ll certainly relate.Zaytoven provides a floating organ-driven beat, not unlike something that would have appeared on Future’s Beast Mode mixtape. This is the latest of many new records we’ve received from the Atlanta jokester recently, dropping of his impressive Trapavelli Tremixtape in August. Make sure to grab that one here.
