Taylor Swift set the internet on fire before people could drink their morning Swig.

Swift — the popular singer-songwriter, who you should have heard of by now — tweeted a video clip that hinted of a new song on the way. The video shows a vault, colored in red, with music playing in the background. Lines — filled with a jumble of letters — fly on the screen.

So, this is all a hint at potential new music. The red color and the vault suggests this new song will be a song from the vault (a term Swift uses to describe previously unreleased songs that were cut from an album) from her “Red” album, which, she said, is the next of her rerecorded albums to release.

But which song could it be? Swift fans have already started to dive into the message. Some fans took all the jumbled words and made crossword puzzles. Others reversed the audio to see if there were any clues. And some went the extra level to slow down the audio and reverse it at the same time, just to see if any hints emerged.

Any theories?

I’d bet this is a rereleased version of her hit “All Too Well.”

For one, the post has the words “casually cruel in the name of being honest,” which is a direct lyric from her song “All Too Well.” So that’s clearly a reference to that song.

Plus, according to Billboard, there have been rumblings of a 10-minute version of “All Too Well” for the album, so that’s clearly a possibility.

New music for the weekend releases at 10 p.m. MDT. We’ll have to see what happens then.
