Taylor Swift posted on Twitter this weekend another brief preview of her new music special for Netflix. "'All Too Well' was never a single, and it always blows my mind that it is consistently one of the loudest songs the crowd sings when I play it," Swift tweeted Saturday. "Moments like this defined the Reputation Stadium Tour for me, and I can't wait for you to see it in full starting at 12:01 AM 12\/31 PST." The post included a 40-second video of Swift performing the song and playing the guitar as concertgoers sing the lyrics along with her. A separate trailer for the special was released two weeks ago. Swift turned 29 this month. Her song "Look What You Made Me Do" also achieved the milestone of 1 billion views on YouTube in December.
