The title is a compressed spelling of song and the French phrase je sais pas quoi, a casual way of saying I do not know what. No clear original recording, artist or year is documented for this soundboard version, so it circulates mainly as a standalone meme audio rather than as a known chart song. French phrases like this travel well in edits because the shrug meaning is easy to guess from tone alone, and the loopable delivery helps creators reuse it for confusion, forgetfulness and deadpan reactions across short videos.
