History. 5 of 8: Amazon's song was in the top 10 of the Christmas chart in 2020 (4), 2021 (10), 2023 (2), 2024 (4) and 2025 (1), and outside it in 2018 (56), 2019 (11) and 2022 (15).
Hunch. The original Step Into Christmas was already number 7 last Christmas, so this new version starts with a song people already look for in December.
The top 10 market resolves on the same chart: YES if Step Into Christmas (Amazon Music Original) is at any place from 1 to 10, NO if it is at 11 or lower or not in the top 100. BBC News and The Guardian settle it if the chart page cannot be read.
We looked for cases where a music streaming service put out a Christmas song of its own that was not on rival streaming apps, before the UK Christmas chart. We found eight Christmases from 2018 to 2025, all of them Amazon Music. Its song was number one once, in 2025. In the other seven years it reached between number 2 and number 56.
