What is the name of or who sings this song from Cruel Intentions: This song comes on when Annette says she doesn't trust herself with Sebastian and then it comes on where you can really hear it when Sebastian comes into Annette's room to tell her how she is turning her back on love. If anyone can help me thanks a lot
