Lowes, Girl singin "Say youll stay..."

Heard the song in Lowes and ive heard it there before. Its a female singer and the lyrics sounded something like "Saaay youuul stay, i neeed to knoooow" Its a softer song and my sister says its somewhat older like 90s. Driving me nuts.

Lyrics i heard were "Say you'll stay" and "need to know" The song title is Sway by Bic Runga. Its also in the american pie soundtrack. All google results have the name wrong so i was seriously confused when i saw "Big Runca" and thought to myself "its definitely not a rap song".
