"New Heart" is a single by Crash Adams. The song was released by Warner Music Canada in 2025.
The song expresses the heartache of a broken relationship. It went viral on TikTok in 2025 through prank videos in which users threw water balloons at passersby. On the platform's Chinese equivalent, Douyin, the lyrics "doctor", "medicine", and "new heart" inspired medical professionals to create dance videos using the song; the metaphor of heartache in the song is reinterpreted literally by the trend.
In October 2025, Sophie Powers was featured on the song as a guest rapper.
