This is song samples “La-La (Means I Love You)” by the popular Philly soul singing group, The Delfonics. Though instead of just using one piece of the song (as most samples do), Ghostface uses the entire thing, modulating his voice to fit the fluctuations of the track.

Ghost would later do another song following this same premise with The Stylistic’s “You’re a Big Girl Now” on Fishscale’s “Big Girl.”
