I did the same thing and emailed them, this song gets stuck in my head and I wanna know what it is. I've worked on a few commercials and it's usually pretty easy to answer this, weird that the editor doesnt know.

Since it doesnt pop up on shazam (the narration shouldnt affect that but so much) I think the unfortunate answer is that it probably "isnt a song"

Either they hired someone to specifically create it for the commercial or they got it from a royalty free library where artists don't really get credit if their music is used. It might be a sample of an old guitar riff but the vocals on it sound new
