Life is full of fundamental, inescapable equations: one plus one always equals two, hydrogen plus oxygen always equal water, and T-Pain plus [insert just about any artist’s name] collaborations will always be instant hits. Chucky Boy, an up-and-coming rapper from Tampa, certainly knows his math. His new single, Ridin Out, is a festive track with a late-90’s feel featuring a hook sung by none other than the hitmaker himself. As its title suggests, the track is a happy-go-lucky tribute to interstate joyriding. Chucky’s three excited verses and T-Pain’s uplifting hook are driven by M. Rell’s likeminded production, complete with a bright string ensemble and celebratory claps. In the end, it all adds up.
