TaeTiSeo just keep giving us early Christmas gifts. (No complaints here!)

Earlier this month, the girls of the Girls' Generation subgroup — Taeyeon, Tiffany and Seohyun — decked the halls by debuting their cheery Christmas clip for "Dear Santa," the title track of their new holiday record.

Rather than a series of tired covers of classics, the new album is a festive blend of throwback-sounding Christmas-themed delights, uptempo bright-pop charmers like "I Like The Way" and "First Snow" and, of course, some beautiful balladry for the snowy season. And to keep the momentum for their latest release going, the girls just unveiled an acoustic take on "Winter Story," the guitar-led, finger snap-filled ballad from the mini-collection.

Backed by two guitar players (and some Christmas trees and festive decorations, obviously), the talented trio tenderly croon their way through the sweet tune, showcasing their talented chops as solo singers — and their ability to harmonize as a group.

Grab some hot cocoa, settle down by the fire (or, maybe more accurately, a warm laptop screen), and indulge in the warm, soothing sounds of an acoustic TaeTiSeo.
