What is the name of that song that goes "millenniiiiiiium"?

I know that this isn't much to work with but I just know that the word millennium is harmonized and its a new-ish song, probably not titled Millennium as I have looked everywhere for a song with this title and they're all old/not what I'm looking for. Anyways, it might be hard but if you know of any new songs that are mainstream-ish, and go something like this, please help me :) Thanks.
