Around the last half of last year I saw a video of a guy on TikTok promoting his song. I remember the video was of him green screening himself onto city scenery. He was doing a little dance which was him pointing and shaking his torso up and down slightly (kind of the dance all babies can do but he was more coordinated). At some point in the video he flips himself around before continuing the dance. I feel like the song released in August or sometime in the summer/early fall.
I cannot really remember the lyrics but they it was kind of back and forth between "I could've done this but I didn't". The vibe of the entire song was him being passively sad at the passage of life from what I remember. He is a one man band, a white dude, and he had hair.
