In an interview with REVOLT, Carey spoke about how it felt to watch the aforementioned track reach the 1 billion stream mark and earn a diamond certification.

"It's an amazing thing and I'm very thankful. I can't believe this song I wrote so long ago when I first started… Christmas songs take a while to permeate the culture, you know what I mean?" the R&B icon said. "It's an honor and, honestly, it's all because of my fans. Even people who aren't necessarily my fans, they're just like, 'Whatever, we like that song.' It's a huge honor and I'm thankful for all of it. The billion streams, the diamond award, all of it."
