The song is based on a sample of the Fugees' 1996 hit single "Ready or Not", which itself was based on a slowed-down sample of the instrumental track "Boadicea" by Enya from her 1987 album Enya. Winans said: "I first heard 'Boadicea' at the end of the movie Sleepwalkers about five or six years ago. It's something I always wanted to produce. Then when The Fugees did it, oh my God, I loved it."
Vibe wrote that "Winans adds a simple stuttering beat that prevents the song from devolving into murky, saccharine Muzak. This is the secret of Winan's magic; the soft touch of the synthesizers and his gentle piano playing blend with the signature sound of the kick and snare – hard, unadorned, punching through the music's gauzy elegiac texture."
The official remix features D-Block rapper Jae Hood, Enya, & P. Diddy. Another remix features Joe Budden, Enya, & P. Diddy. An answer to this song, "You Should Really Know", sung from a female perspective, was released later in the same year as Winans' single. Created by the producers The Pirates, it featured Shola Ama, Naila Boss, and Ishani. It used the same Enya sample as the original. Although it did not achieve the level of success Winans' single did in the U.S., it was a big UK triumph, peaking at #8 in the singles chart. Later on, another answer song called "I Already Know" sung by Noelle was released and had the same background melody as the original song. Puerto Rican-American R&B group Nina Sky also recorded their own version of their song entitled "Time to Go" featuring rapper Angie Martinez.
