Taylor Swift went back to her roots when she rehearsed her Fifty Shades Darker track, "I Don't Wanna Live Forever" in the studio. The singer recently took her pop hit down a few notches by performing it acoustically. Not only does the video remind us just how talented she is (those guitar-playing skills), but the tune is extremely reminiscent of her Fearless album. Coincidentally, Zayn also posted an acoustic version of the song on YouTube. Is it possible that these two are gearing up to perform their duet during Swift's pre-Super Bowl concert? We sure hope so.
