What is the Cool Kids x Tumblr Girls trend?

A mashup audio trend pairing two nostalgic tracks. A general-use sound with no fixed text-overlay format that suits unhurried, low-key footage. Brands use it to back product detail shots and candid lifestyle clips without text commentary.

Where did the Cool Kids x Tumblr Girls trend come from?

The "Cool Kids x Tumblr Girls" trend is a TikTok audio mashup combining two mid-2010s tracks: "Cool Kids" by Echosmith, originally released on May 31, 2013, and "Tumblr Girls" by G-Eazy featuring Christoph Andersson, released on February 23, 2014 as the third single from the album These Things Happen. Both songs experienced separate TikTok revivals years after their original release: a sped-up version of "Cool Kids" drove more than 1.3 million TikTok videos in 2022, while "Tumblr Girls" surged on TikTok in late 2023 and peaked at number 14 on the TikTok Billboard Top 50 by March 16, 2024. The mashup edit pairing the two tracks circulates as a general-use sound for slow, contemplative footage that evokes the Tumblr-core aesthetic revival on the platform. No authoritative source has identified the original creator of the mashup sound.
