What's a song that changed your brain chemistry?

Basically the title. What's a song that kick-started a phase of yours? Or changed your personality? I have multiple:

-i remember watching the MV of "Finesse" by Bruno Mars in 5th grade, and I immediately fell in love with it. I remember going, "This. I want to have this vibe."

-i was watching Hamilton for the first time in 2020. I thought it was entertaining. But then, when "Ten Duel Commandments" started, I remember feeling like, "Shit, this is really good!" My Hamilton phase started when the best dropped.

-lupe Fiasco's "Daydreamin'" had me hooked right off the bat as soon as the beat dropped and Lupe started rapping.
