I believe this an 80's song... and maybe redone...?

At work I hear this song and I cannot hear the words very clear, but I do know that a female sings the song. The song is moderate in speed, there are quite a few of harmonics. The thing I can remember the most is hear a long "Laaaaaaaaaaaa, la, la, laaaaaaaaaaaaaaaaaa" and I just think it sounds amazing. Maybe someone can help me? thanks!
