[TOMT] underrated and obscure song that has female voices that go "sing it"

There's this song that I cannot find anywhere or don't know the name of, I heard it like 4 times, it was in a deleted bfdi ripoff video, in a numberblocks video, in a Shiloh and bros video known as "Why It's Expensive Being A Girl", and a Lewis Qball Nickell video known as "Tourette's on Helium", I've been trying to find the same song but I cannot find it, can someone find it for me and solve it? I wanna see the name of that song
