Well, because new music seems imminent, fans are speculating that some of the clothes she's worn over recent months are actually very clever hints at the possible theme of TS7.
The theorising began with the costume party that Taylor threw for some of her showbiz pals on New Year's Eve. The theme was "childhood heroes," and she dressed as Ariel from The Little Mermaid.
But then fans began to notice that mermaids have popped up several times over the past year.
For example, she wore this jacket with a mermaid motif in the magazine which was released alongside physical copies of Reputation back in November 2017.
And, at the end of her Reputation tour documentary which was released on New Year's Eve, Taylor can be seen in the blooper reel wearing a T-shirt emblazoned with two mermaids.
So, of course, theories have sprouted. Some people think that her new album will have a mermaid or fantasy theme.
Others have noted that Ariel "transforms" at the end of The Little Mermaid, and so perhaps Taylor will transform with the release of her new album.
Some have investigated the symbolism of mermaids and found some pretty interesting results — namely that they're heavily associated with love. And, given that Reputation was an album filled with love songs and her relationship is still going strong, it stands to reason that TS7 will follow a similar theme.
While others think the album will actually have a broader nautical theme thanks to Taylor's love of the sea.
One person suggested that rather than an album, the appearance of mermaids point to a song offering a modern twist on The Little Mermaid, in the way that "Love Story" was a re-telling of Romeo and Juliet.
And it might be a bit of a reach, but back in May last year fans went wild over the fact that Taylor had the word "Eternal" hidden in her dress at the Billboard Music Awards.
However, a couple of people have taken the theory even further, speculating that perhaps Taylor will play the role of Ariel in a live-action version of The Little Mermaid.
But some people are pointing out that fans have been very wrong when it comes to guessing the name and concept for Taylor's albums in the past.
So, time will tell as to whether this whole mermaid thing is a reference to her new music, a simple coincidence or an artful troll from Taylor.
