The song has re-entered the Billboard Holiday Songs Chart on a regular basis with it peaking at No. 3 on 7 December 2019. As of 25 November 2016, total US sales of the digital track stand at 751,000 downloads according to Nielsen SoundScan, placing it 10th on the list of all-time best-selling Christmas/holiday digital singles in US SoundScan history. The song debuted at number 50 on the Billboard Hot 100 in the chart dated 7 January 2017, after George Michael died. In December 2018, the song re-entered the Hot 100, reaching No. 25 in January 2019, and then a new peak of No. 11 in the first issue of 2020.
