Singer-songwriter and producer duo KTJ & CARLY have spent the last few years perfecting the art of the pop banger, and their latest single, “Good Day,” is no exception.
On “Good Day” KTJ & CARLY transform post-relationship bitterness into a euphoric, windows-down anthem that embraces their most chaotic instincts yet. They take a delightfully unhinged approach to post-breakup catharsis mingling a driving drum beat and a funky 20th-century infused bass line into the mix. With a mischievous wink and an earworm chorus drowning in their emblematic harmonies, “Good Day” revels in the chaos of revenge fantasies, from the juvenile (TP’ing an ex’s house) to the downright felonious (setting their car ablaze—allegedly). It’s the perfect soundtrack to bad decisions, blending high-octane production with a darkly comedic edge. If “Good Day” is any indication, KTJ & CARLY are about to make heartbreak sound better than ever.

“Good Day” has such a fun, chaotic energy. What inspired you to channel post-breakup bitterness into such an upbeat, almost mischievous track?

Funny enough, when we were in the studio, we were like, “I’m so sick of writing sad songs—let’s write something happy for once!!!” We came up with the title Good Day first, and, naturally, found a way to turn it into a revenge song. It was almost inevitable. We started with the opening line—saw you with your new girl, laughing in an Erewhon—thinking it would be a song about moving on. And in a way, it still is. But as we kept writing, it took on a whole new life. It was such a fun one to create. — CARLY

Obviously, the best revenge is indifference. But we wanted a song that goes to the extreme—something that acts as an outlet for staying indifferent. — KTJ

The lyrics of “Good Day” explore some pretty wild revenge fantasies. How did you strike the balance between dark humor and emotional catharsis while writing the song?

The humor comes from the fact that we would never actually do any of these things. Like, these are deeply illegal. But when someone hurts us, our minds sometimes spiral into these dark, petty places, even if we’d never act on it. That’s where the catharsis happens—taking those bad thoughts and turning them into something fun. — CARLY

I think life—like this song—is a lot easier when you can laugh at it. Sure, this person broke my heart, and yeah, it sucks. But karma’s coming for them anyway, so why not joke about it? — KTJ

The production on “Good Day” is dynamic and layered, with a funky bass line and driving drums. How did you approach the sound design for this track, and what influences shaped its sonic identity?

We were really inspired by the band the beaches—I really love the high energy and drums they use. We co-produced with Arieh from PinkSkies (who we met on tour with Tim Atlas), and he brought a psychedelic, fun flare that we knew we had to blend into our KTJ & CARLY sound, and we think it turned out really cool. — KTJ

You mention that this song embraces your “most chaotic instincts yet.” How did it feel to lean into that chaos creatively? Did it challenge you in any way as songwriters or producers?

Leaning into chaos actually felt pretty natural. At the end of the day, we’re just telling a story. This song, while inspired by real emotions, is more of a fictional tale we created. And sometimes, storytelling gives you the most freedom—lyrically and musically. — CARLY

It felt so good. Revenge always leads to disaster, and it’s definitely not something to encourage, but it’s fun to play pretend. The biggest challenge was the final stretch—those last tweaks before sending it off, making sure the vocals and production were locked in. — KTJ

Your harmonies have always been a signature part of your sound. How did you approach the vocal arrangement for “Good Day” to make it feel both catchy and emotionally charged?

Vocally, the song came together pretty effortlessly! We just kept throwing out different ad-libs and harmonies, seeing what stuck. I think where our voices sit in this song, especially toward the end, gives it this almost primal, scream-like energy. That’s what I was channeling in the outro—I want people to be yelling this song by the end, screaming it at the top of their lungs. — CARLY

After we built the core melodies, we just kept experimenting. We had so much fun making this track, and I think that comes through. When you sing from the heart, it translates to the listener—and hopefully makes their day a little better. — KTJ

The song mixes playful, almost juvenile acts of revenge with more intense imagery. Were there any specific personal experiences that influenced this creative contrast?

For the record, I have never hotwired a car or framed someone for murder. But I have tied my friend’s shoes together as a prank. I know someone who signed their ex up for a Scientology mailing list. They’re very persistent—it was probably really annoying for him. — KTJ

I think the most real parts are before the revenge—seeing your ex in public with someone new, seeing them in a new car, getting those random texts from their family. The emotional frustration of it all. But for the most part, it’s all fiction. — CARLY

You’ve described “Good Day” as a post-breakup anthem. How do you hope listeners connect with the song emotionally—whether they’re in a similar situation or not?

I just hope anyone who’s struggling to move on finds solace in this song. More than revenge, I think the heart of it is about finding peace for yourself. This song is about your good day, whatever that looks like. — CARLY

When someone listens, I want them to take away the feelings from someone who did them really dirty and has given them so many shitty days, and replace it with the knowledge that they’ll have a shitty day at some point and hopefully have some revelations. I want listeners to have the best day ever.  – KTJ

How did working together as both sisters and creative partners influence the direction of “Good Day”? Did you have any creative disagreements while shaping the song’s tone or message?

Honestly, before we wrote this song, we were feeling stuck. We were questioning a lot—if we were doing the right thing, if we were moving in the right direction. But after writing Good Day, we felt so re-inspired. It reminded us why we love doing this. There weren’t really any creative disagreements on this one—we just ran with ideas, and if something didn’t work, we pivoted. — KTJ

March 14th marks the release of “Good Day.” How does this single set the tone for what’s next for KTJ & CARLY? Can fans expect more of this chaotic, high-energy vibe on future releases?

We have so much in the works. I’m beyond excited for this year. There’s definitely more high-energy, fun stuff coming, but also a lot of deeply lyrical, storytelling-driven songs. It’s gonna be a good mix. 

If you had to describe “Good Day” in three words, what would they be—and why?

Live laugh love. – KTJ

Petty, unhinged, and liberating! – CARLY
