Taylor Swift certainly knows how to build anticipation. Her upcoming album, Reputation, won’t be out for another two months (on November 10, if you want to mark your calendar), but her first two singles from it have already launched 1,000 fan theories from Swifties unwilling to let mere music keep them occupied. These intrepid pop-culture detectives have been looking for clues to the track list everywhere, even in a minute-long ad for AT&T that stars Swift and a few iconic guitars.

The ad features Swift in the studio getting ready, it’s implied, to record some music for her upcoming album. And Swift fans, who were definitely rock stars at those Highlights “Find the Difference” puzzles, have noticed (and shared their observations on Tumblr) that in the back of the studio there are a few of Swift’s famous guitars from various stages of her career—from the brown acoustic guitar of her early days to the red electric ax more connected to her pop transformation. The appearance of the guitars, coupled with the line up of “ex” Taylors at the end of the “Look What You Made Me Do” video, have lead some fans to believe the tracks on Reputation might all correspond to those ghosts of Taylor past.

The AT&T video also features Swift playing a new white acoustic guitar, giving Swifties hope that the album will feature at least one acoustic track, despite the fact that the “new” Taylor seems to be in love with beats that are better to work out to than they are a soundtrack for long periods of staring into the middle distance. There’s also some speculation that the “possible” acoustic song could be the much mythologized (and possibly nonexistent), 10-minute-long version of “All Too Well” off of Red.

If you need more Reputation speculations, theories, and predictions to occupy your days as you count down to the release, there’s no shortage, from snake-y connections to an album split between the old Taylor Swift and the new. So break out your headphones and your oversize magnifying glass. Those videos aren’t going to analyze themselves.
