hey, i just saw the movie and i wondered if someone here could help me

theres a song they play twice in the movie as the kind of love theme between matt and danielle, when they first kiss at the big party and then again at the prom... i know ive heard it before, but i cant remember the name or artist of it, and i dont think it was included on the films soundtrack, which i just checked
if anyone out there has seen the movie and knows which song im talking about, can you please either post back here or email me at sir_gizmo@hotmail.com

thanks a lot
