K-PAC Day 6: The Barberettes - Winter Wonderland (no, not the one you're thinking of). The Barbs Xmas mini-album just came out yesterday, and if smooth, close harmony girl groups are your thing, it's well worth checking out.
T-ARA - Day By Day/Sexy Love (Drama version edit). Why make different videos when you can combine 'em into a 20 minute epic about sisters, swords and superpowers? YMMV depending on how you feel about trashy post-apoc, but at the very least it's a great excuse for Eunjug, Hyomin and Jiyeon to strut around yelling "Dani!" a lot while looking amazing. Best bit: Eunjung being a complete badass on the dancefloor 15 minutes in.
