It's the first track on her album, titled "I Forgot You Existed."
Right away, the verse alludes to the darkness she felt after the backlash from Kanye's "Famous" song, which re-sparked their feud.
How many days did I spend thinking 'Bout how you did me wrong, wrong, wrong? Lived in the shade you were throwing 'Til all of my sunshine was gone, gone, gone," Swift sings.
As The Blast reported, she recently opened up about having to restructure her life following the infamous recording Kim Kardashian released.
Also in the first verse is a reference to Drake, which fans point out is another artist who's had beef with Mr. West in the past.
In my feelings more than Drake, so yeah / Your name on my lips, tongue-tied / Free rent, living in my mind.
Remember, Kanye unleashed on social media and accused Drake on Twitter of threatening his family last year.
In the chorus, Swift sings about a lightbulb going off in her head and one day, "I forgot that you existed."
The hook's pretty catchy and says things like, "It isn't love, it isn't hate, it's just indifference."
Then she appears to sneak in a diss about how Kanye and Kim kept their feud in the press -- from the reality star using a snake emoji at every opportunity to even bringing their battle to an episode of "KUWTK."
Got out some popcorn as soon as my rep started going down, down, down / Laughed on the school yard as soon as I tripped up and hit the ground, ground, ground / And I would've stuck around for ya / Would've fought the whole town, so yeah / Would've been right there, front row even if nobody came to your show.
Swift's lyrics appear to say she's over their feud and ready to move on from the Kim/Kanye drama -- and fans are LOVING it!
