I'm on a mission, a few days ago (as of April 4, 2024: East Coast USA) there was an ad which lasted about 3 minutes long, with no advertising being done - it simply played clips from the anime Serial Experiments Lain and had a song which I was not able to identify.

I want to find this ad to identify the track which was playing. I suspect it was the Opening theme for the anime itself, but I can't confirm that until I find the ad itself again.

Thank you in advance.
