Alright, even though I got a clip it seems impossible find this song.
Ive asked many people, they recognized it but cant find out what song or artist it is.

HERE IS THE CLIP

The lyrics goes like "and then somebody, then somebody you love loves someone else too".
If you have any idea please let me know.

Sorry for using megaupload as host, cant find any better.

Edit: From the beginning the song was helium pitched, so this might isnt the original speed. But it is/sounds close.
