Personalized Christmas Song with your faces

Most Christmas songs are about someone else. This one has your family's names in it and their faces singing it.

The page loads the Christmas lounge: a decorated tree with warm fairy lights, a brick fireplace with stockings and snow falling outside the window, with a vintage mic on a floor stand in front of each singer. The Melodic beat, warm pop and R&B at about 100 BPM, means they sing the verses and finish the hook together in harmony.

The Christmas lyrics come preloaded. Keep them, or swap in the names, the burnt cookies and the uncle who always falls asleep after dinner.

Cards are nice. A short video of Grandma and Grandpa singing by the tree is the one that gets forwarded to every cousin.

It's a vertical 9:16 MP4 with no watermark, made for phones, so it's easy to send over WhatsApp, text or email. Post it in the family group chat on Christmas morning, or send it to the people who can't make it home this year.

Making a few? The Duo Pack is $29 for 50 credits, about 5 songs, and pack credits never expire, so any leftovers carry over to next December.

Any two people who said yes. Casts that work well:

• Grandparents singing a greeting to the grandkids.
• You and your partner as this year's holiday card.
• Siblings singing to Mom and Dad, with a joke about who's the favorite.
• Two coworkers for the office party, with a clean verse about the year.
• Roommates or friends spending Christmas together.

Use clear, front-facing photos in good light, with shoulders visible and no sunglasses or heavy filters. For one person singing alone, switch to Solo mode.

Prefer bars to carols? Switch the beat. Trap gives you hard 808s at about 140 BPM, and the two of you rap and shout the hook. Boom bap brings dusty 90s drums and piano at about 90 BPM for a laid-back holiday rap.

You can change the language too. English works best, Chinese works well, and other major languages usually work, so a verse for the grandparents in their own language is worth a try. Every tune is original, so it never borrows from an existing Christmas song.
