"Sleigh Ride" is a traditional Christmas song that was covered by Karmin. It was recorded in November, as confirmed by the couple via Twitter, and officially released on November 28th, 2012. It is currently available for purchase free on http://www.coach.com/Karmin.
A music video was filmed for the single and released the same day.
This song is the first Christmas song by Karmin; supposedly, it is a digital download single only and will not be available on a Christmas album, as Karmin has no plans of making one yet, as far as the fans know.
The song, while sticking to the traditional lyrics of it, also has a few new elements not included in the original version, including a rap from Amy and Nick singing "Giddy-Up, Giddy-Up, Giddy-Up" repeatedly as the song's hook.
