Taylor Swift gave her fans (and Katniss die-hards everywhere) an early Christmas gift late Thursday when she tweeted the link to her new song for The Hunger Games soundtrack.

"Something I've been VERY excited about for a VERY long time is going to be happening VERY soon," she tweeted shortly before linking to the track on iTunes. "Safe & Sound" is a collaboration between the country-pop singer and alt-folk duo The Civil Wars.
