For those of you who need a refresher, music plays a huge part in If I Stay. Both Mia (Chloe Grace Moretz) and her boyfriend Adam (Jamie Blackley) are talented young musicians. Adam is part of an indie rock band and in the book they are called Shooting Star. For the film, however, they had to change the band name to Willamette Stone.Warner Brothers is launching a new #IfIVote campaign for fans to choose their favorite song out of four exclusive Willamette Stone songs! Listen to the sneak peek of each song below and vote for your favorite on the official Facebook post
