I'm sure you'll know by now that on Friday, Taylor Swift released the lead single from her highly anticipated seventh album. It's called "Me", and obviously, it's a bop. Republic / youtube.com She's keeping all the info about the rest of the album ~very~ under wraps, but Taylor has revealed a couple of interesting details in radio interviews over the last few days.

First of all: Yes, the album is finished. View this photo on Instagram instagram.com "I like to be able to have the information to give [before I release a lead single], and when I have something done, that's when I can fully plan and make it the most fun experience for fans," Taylor said in an interview with Zach Sang. "I'm really proud of it. I can't wait for more things to come out."Taylor also revealed during a HITS Radio interview that she's already played the album to her closest friends, and it's a mark of how much she can trust them that no one has publicly spoken about it. 2. Taylor started working on TS7 almost immediately after finishing the Reputation tour in November. View this photo on Instagram instagram.com "I started working on it pretty much immediately after [the tour], but I did have a lot of ideas I'd been cultivating while I was on tour," she told Kiss 92.5. I pretty much got into the studio when I got off tour and stayed there. I was very ready to make the next thing. I knew exactly what I wanted to make next." 3. The countdown theory may not have been legit — and Taylor is well aware of it — but we were right about certain Instagram posts marking the beginning of the TS7 era. View this photo on Instagram instagram.com "That [fence] picture... I really just was trying to change up my Instagram aesthetic to get ready for the new album," Taylor laughed during an interview on Fox Melbourne. "I was just posting pastel pictures to try to go from a dark to a light and kind of show them what the colour scheme would be for the next album." 4. The album's lead single — "Me" — isn't meant to take itself too seriously, and was written as a "self-love mantra".

It's about embracing and feeling, at times, like you're irreplaceable," Taylor said. "I think with a pop song you have the ability to get it stuck in people's heads, and I just want it to be a mantra that is much more self-love than what we often times feel, which is self-loathing and insecurity." 5. According to Taylor, she didn't just include a few Easter eggs in the video for "Me" — literally everything in the video is foreshadowing what's to come with the album. View this photo on Instagram instagram.com "Every single choice we made was to foreshadow something that will happen in the course of the album," she said on HITS Radio. "When I was like 16 and I put out my first album, I put codes in the lyric jacket of the CD. I capitalised certain letters, and I was like, 'I wonder if they'll figure out that it spells out a code', and they did immediately. From then on I've known that [my fans] like to play games with music. I like for music to be as much of an event as possible." 6. In fact, some of the clues won't become clear for literally months — until Taylor goes on tour. Republic / youtube.com "[Brendon and I fight] in French, and that's another clue that will probably be revealed in the next few months," she said during an interview on KIIS FM. "A lot of the Easter eggs I put in the videos are ones that I want to age well. Some of them I want to be revealed when people watch the video initially, and then some of them people won't realise the meaning of until about six months to a year from now when we go on tour. That's how far ahead I've been planning this album."She also said in an interview with Ryan Seacrest that some of the clues in the video are references to specific lyrics on the album. 7. While "Me" wasn't the first song that was written for the album, it immediately became clear to Taylor that it should be the lead single after she wrote the chorus. View this photo on Instagram instagram.com "It actually wasn't the first song that we created, but as soon as I wrote the chorus I pretty much knew that this was really special," she told Zach Sang. 8. However, the song isn't necessarily a representation of what's to come with the rest of the album.

There isn't ever one song that can just sum up what the album is," Taylor explained. 9. We do know that we can definitely expect something entirely different from the Reputation era. Republic / youtube.com In an iHeartRadio interview, Taylor described this upcoming era as "mischievous", "glittery", and "a little bit more playful than last time". 10. But that doesn't mean the album is going to be all happy songs. Republic / youtube.com "The album has lots of different emotional tones to it, in the same way that a person is never going to just be happy all the time," Taylor said. "When I make an album, it's never just going to be a happy album."She went on to say the album will contain a "diverse emotional spectrum" of songs — so it looks like the "All Too Well" stans could have something to look forward to. 11. In fact, Taylor says the rest of the album is "very different" from the lead single, and contains some "in-depth lyrics that [she's] really proud of". View this photo on Instagram instagram.com "This album is a pretty big story," she explained. "There's a lot to say. Like I said, a lot of the time I'll pick a first single because I like the feeling it conveys, knowing that there's a lot more on the album that's very different from that first single." 12. Taylor hinted that we may be getting some more singles before she drops the entire album. View this photo on Instagram instagram.com "It's good that you can put out a lot of music before an album comes out, and kind of give people a taste of what the album actually is," she told iHeartRadio. 13. And while she's not ready to reveal the album's title just yet, she did say some fans have guessed correctly based on clues in the video.

"I'm not going to tell you who." That's all, Swifties! And remember: Spelling is fun!
