One Sweet Day [SEP] Introduction
"One Sweet Day" is a song by American singer Mariah Carey and R&B group Boyz II Men. The song was released on as the second single from Carey's fifth studio album, "Daydream". The artists co-wrote the song with Walter Afanasieff, who co-produced it with Carey. 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.
