 His mother was the late American singer Phyllis Nelson, best known for the songs "I Like You" and "Move Closer".

 "One Sweet Day" was produced by Carey and Afanasieff for her fifth studio album, "Daydream," and was released as the album's second single on  14, 1995 (1995--) .
 The song speaks about the death of a loved one, how the protagonist took their presence for granted and misses them, and finally about seeing the person in heaven.
 Both Carey and Boyz II Men wrote the song about specific people in their lives, being inspired by sufferers of the AIDS epidemic, which was globally prevalent at that time.
"Thank You" is a New jack swing song released by American R&B/soul-singing group, Boyz II Men in 1995.
 "Thank You" was co-produced by Dallas Austin and Boyz II Men, and the song was released as the third single from Boyz II Men's second studio album, "II".

 The album version of the song consists only of sounds created by the human voice, creating an almost a cappella sound, bringing to mind (and, at one time, quoting) one of their first hit songs, "Motownphilly".
Blayse was a short lived American R&B supergroup, which consisted of Terrell Phillips (formerly of Blackstreet), Marc Nelson and Tony Grant (formerly of Az Yet) and Gary "Lil G" Jenkins (formerly of Silk).
 The group name is an acronym developed by combining the names of the members' former group affiliations ("BL" from Blackstreet, "AY" from Az Yet, "S" from Silk, "E" added to denote the phrase "Everything You Could Want").
"Let It Snow" is a song co-produced and performed by American contemporary R&B group Boyz II Men, featuring vocals from fellow American contemporary R&B singer Brian McKnight.
