Taylor Swift 'Eyes Open': Singer Performs New 'Hunger Games' Song Live (VIDEO)

Taylor Swift may be the music industry's top earner, but what you may not know about the country darling is that she's also a "Hunger Games" superfan. Swift has not one, but two original songs on anticipated "The Hunger Games" soundtrack, including one of her signature power anthems -- "Eyes Open."

"Eyes Open" leaked last week, as well as a track from Kid Cudi, titled "The Ruler & The Killer." However, New Zealand fans got an extra-special treat Sunday night when Swift performed the track live for the first time.

"I'm really excited about it… but, I mean, you don't think I'd get in trouble if I played it now? Probably not, right?," Swift teased the thousands of screaming concertgoers who packed Auckland, New Zealand's Vector Arena for the last date of her 13-month Speak Now World Tour.

Swift's first "Hunger Games" contribution, "Safe & Sound," featuring The Civil Wars, was released in December.

Watch Swift perform her new single "Eyes Open" above. "The Hunger Games" soundtrack, featuring music from Swift, The Civil Wars, Arcade Fire, The Decemberists and Miranda Lambert, hits shelves on March 20.
