 Despite the low download sales of the single, "Let's Just Do It" received a very positive review from "Billboard" magazine.It says "The energy that made the trio's upbeat singles international smashes is evident here, along with Lisa's essence—a reminder that TLC was among the most successful female R&B groups of all time.Originally recorded in 1998, the Heavy Weights and Marcus DL's production builds a catchy and contemporary rhythmic structure."
