“I love ‘Fall in Love at Christmas’ because I love that it’s a departure—it’s a love song, and then it’s a spiritual song,” the 52-year-old tells PEOPLE in this week’s issue. “I say, ‘We pray at this Christmastime,’ like, love is something we need to give away. Let’s give love away. It’s really trying to say that we’re in a really screwed up place in the world. We all need grace upon grace upon grace.”

Carey, 52, says she’s “extremely happy” with how the song — which she co-wrote — has been received since its Nov. 5 release, and explains that part of its appeal lies in the fact that its lyrics are reflective of her real-life Christmas spirit.

“I have my own favorite lyrics from this song. I remember just like, the very first night I started playing with it, and messing around with the idea… There’s a line in the body of the song that goes, ‘And the candles glow/I’m awake but no one knows/Just waiting patiently to hear the sleigh bells jingle/There they go.’ To me, that is a real moment that I experience every year,” she says. “I just love these moments where you’re able to give a glimpse of yourself to the fans.”

As someone who lays claim to the ultimate addition to the holiday songs canon, does Carey feel pressure to measure up to its success with subsequent holiday releases?

“I don’t feel pressure in writing songs, whether it’s Christmas songs or other songs, because if it’s something that you’re feeling, then that’s what you’re writing,” she says. “As a writer, that’s how I kind of look at things. I guess other people are like, ‘Whoa, she’s competing with ‘All I Want for Christmas Is You.’ No, I’m not. ‘Cause I can’t. I personally can never compete with my own song.”

The five-time Grammy winner says she got her love of the season from her “festive” mother — and has certainly passed down the passion to her 10-year-old twinsMoroccan and Monroe.

“These guys are honest and I was really happy when I watched it back,” she says of her kids. “‘Cause honestly, when you’re in a 60-lb. dress, you can’t be looking back to check like, ‘Okay, what kind of face is Rocky making right now? What kind of thing is Monroe doing?’ So it was really sweet because they do say they love it. They think they love it more than me, [but] we came to the conclusion that we all love it the same amount.”

“It’s just honestly, it’s a magical time for me. It really is my most favorite time of year,” the superstar says. “[But] I also love summer, I love a lot. It’s not just like, ‘Oh, I’m only emerging from the sea at Christmastime.’ Honestly, that stuff makes me laugh and i live for it and the truth is if I had to do that, I would do it.”
