Girl's Generation member Tiffany's song, "Because it's You", for the 'Love Rain' OST has been heard in a few scenes of the drama.

The song appears in the fourth episode of 'Love Rain.'  In the first scene, Jang Geun Suk embraces YoonA but she pushes him away.  The second scene also sees YoonA turn her back to Jang Geun Suk.

Tiffany's amazing vocals add to the emotions that run through the scenes, and has fans anticipating the release of the full track.

With all the talk about YoonA and Yuri going up against each other in 'Love Rain' and 'Fashion King' respectively, we shouldn't forget about the battle between Tiffany's "Because it's You" and fellow member Taeyeon's "Missing You Like Craz" for 'The King 2 Hearts' OST.
