Nostalgic Autumn Playlists: The TikTok Trend Replacing Brat Summer This September

Short answer: “brat summer,” the loud, messy, neon-green aesthetic tied to Charli XCX’s 2024 album “Brat,” has given way to a softer, sepia-toned mood on TikTok this fall. Creators are calling it a “nostalgic autumn” or “cozy autumn” playlist trend, and it’s built around wistful, acoustic-leaning tracks, old movie audio clips layered over quiet visuals, and a general shift away from party-coded pop toward something that feels more like flipping through an old photo album. Below is what’s actually driving that shift, which songs and sounds are showing up in these playlists right now, and how to build one yourself if you want in on the trend.

What does “nostalgic autumn” actually mean on TikTok?

It’s not an official genre or chart category. It’s a seasonal aesthetic label, the kind TikTok generates every few months (think cottagecore, dark academia, coquette, or “tomato girl summer”), and it describes a specific combination of things: slower, dreamier songs, muted amber and brown color grading, and content themes built around memory, comfort, and the passage of time. Instead of dance challenges or hype-driven audio, the “nostalgic autumn” wave leans on layered sound, often a wistful song mixed underneath a spoken line pulled from an old film or TV clip, plus quiet footage of things like walking through fallen leaves, making tea, or looking through old photos.

The “brat summer to nostalgic autumn” framing that’s circulating isn’t really a rivalry between two songs or artists. It’s a shorthand for how TikTok’s dominant mood swings from season to season, and this particular swing, from something brash and current to something soft and backward-looking, tends to happen every year once September hits.

Where the “brat summer” comparison comes from

“Brat summer” started in June 2024 around the release of Charli XCX’s album “Brat,” and became shorthand for a specific kind of confident, unfiltered, slightly chaotic energy, reinforced by the album’s stripped-down lime-green cover art. It stuck around long enough to become a genuine cultural reference point, including getting used in U.S. political commentary that summer. By the time autumn arrives each year, though, that kind of high-energy aesthetic typically loses ground to cozier, more reflective content, and creators like to mark the handoff with a “goodbye summer, hello fall” framing, even when the specific summer aesthetic in question has already changed year to year.

The songs actually anchoring nostalgic autumn playlists right now

A few tracks and audio clips have been recurring across “cozy fall” and “nostalgic autumn” TikTok content heading into September 2026:

Beyond individual viral picks, a fan-curated fall playlist format has been circulating with songs like Caamp’s “All the Debts I Owe,” Noah Kahan’s “Call Your Mom,” Hippo Campus’s “Warm Glow,” Lord Huron’s “Meet Me in the Woods,” and Tyler Childers’s “Feathered Indians.” These aren’t chart hits from this specific week, they’re older folk-pop and indie tracks that keep resurfacing every autumn because their acoustic, melancholic tone matches the mood creators are going for. If you’re building a playlist for this trend, older songs with that same warm, slightly sad, acoustic-guitar-and-strings quality will generally fit better than anything upbeat or club-leaning.

How this trend differs from a typical “fall playlist”

People have made fall-themed playlists on TikTok for years, full of generic pumpkin-spice and sweater-weather content. The “nostalgic autumn” version happening now is a bit more specific in tone. It’s less about celebrating the season itself and more about using the season as a backdrop for looking backward, at childhood, at old relationships, at who you used to be. That’s why the audio choices skew toward songs already associated with memory and longing (Mazzy Star, Lord Huron) rather than anything written specifically about fall.

How to build your own nostalgic autumn playlist

1. Start with one or two anchor tracks that already carry a wistful tone. Songs like “Fade Into You” work because the mood is already built in; you’re not fighting the lyrics or production to make something feel nostalgic.
2. Mix eras deliberately. Part of what makes these playlists feel “nostalgic” rather than just “chill” is jumping between decades, a 1990s dream-pop song next to a 2020s indie-folk track next to something from your own personal high school era.
3. Lean acoustic over produced. Guitar, piano, and light percussion tend to fit this aesthetic more naturally than heavily produced pop or hip-hop, even upbeat versions of it.
4. Watch for audio mashups, not just songs. A lot of what’s circulating isn’t a song alone, it’s a song layered under a short spoken clip (a movie line, a voice memo, an old interview snippet). If you’re making content rather than just listening, that pairing matters as much as the track itself.
5. Keep the visual pairing in mind. This trend is as much about the video content as the audio: warm color grading, natural light, and slower pacing tend to reinforce the mood far more than any specific song choice does.

Frequently asked questions

Is “nostalgic autumn” an official TikTok trend name, or just something creators are calling it? It’s an informal, creator-driven label rather than an official TikTok category. You’ll see it phrased slightly differently depending on the post, sometimes as “cozy autumn,” “autumncore,” or “nostalgic fall,” but they all describe the same general mood shift.

Is “brat summer” actually over? The specific 2024 Charli XCX-driven moment ran its course well before this fall, but “brat summer” has stuck around as a general reference point people use to describe any loud, confident summer aesthetic, even in years when the actual soundtrack driving that mood is different. The “goodbye brat summer” framing this September is more about marking a seasonal mood shift than announcing the literal end of a specific 2024 trend.

What kind of songs should I avoid if I want a playlist to fit this aesthetic? Anything overtly upbeat, dance-oriented, or built around a viral hook tends to break the mood. The trend leans on songs that feel unhurried and a little melancholic rather than songs engineered for a dance challenge.

Do these songs have to be newly released to count? No. Several of the tracks anchoring this trend, including Mazzy Star’s decades-old “Fade Into You,” aren’t new at all. Part of what makes a song fit the “nostalgic” label is that it already carries some cultural memory attached to it.

Where can I find more songs that fit this mood? Beyond TikTok’s own sound pages, look for existing “fall playlist” or “autumn indie” playlists on Spotify and Apple Music, then cross-reference which tracks are also showing up as trending audio on TikTok. That overlap is usually a good signal for what’s actually circulating versus what’s just generically fall-themed.
