I know this week is supposed to start concert edition, but I'm really in the Christmas spirit, so I still want to share some of my favorite Christmas tunes :]
Glee - Baby, It's Cold Outside
Hate me all you want for loving Glee, but I do. Come on, people, how can you not love Blaine and Kurt together? They're adorable, and so is this song (when they sing it).
The Christmas Can-Can - Straight No Chaser
Now to continue with the A Capella-ish theme we have Straight No Chaser. I really love their Christmas music. The funny like what's above and 12 Days is awesome, but so is their regular traditional stuff. You should definitely look up some of their traditional stuff too if you're a fan of A Capella :]
