Swift's new single catches music fans by surprise
Taylor Swift has released new single Ready For It, just over a week after she dropped her comeback song Look What You Made Me Do.
The pop star surprised fans as a clip from her upcoming track was played during an American football game between Alabama and Florida State.
The song was made available hours later and is the second release from her forthcoming album, Reputation, which will be out in November.
The lyrics appear to be about a former flame, as the song opens: "Knew he was a killer. First time that I saw him. Wonder how many girls he had left and left haunted."
Within hours it was number three on the iTunes chart.
