Glu

We last heard from Usher when he appeared alongside City Girls on their delightfully frothy “Good Love” track last summer. With “Glu,” Usher slows down the tempo several notches to deliver a downright nasty ode to both pairs of lips. Written and produced in collaboration with Lil Jon, Avila Brothers, and Sean Garrett, “Glu” finds Usher walking in the spirit of Prince.
