#1 to Infinity lines up the eighteen songs that had taken Mariah Carey to the top of the American Billboard Hot 100 by 2015, in chronological order from Vision of Love in 1990 to Touch My Body in 2008. A nineteenth track, the then-new Infinity, closes it. The compilation originally appeared in 2015 and accompanied her residency at the Colosseum at Caesars Palace in Las Vegas, where she performed that same run of songs.

This edition is a 2-LP.
