What song do you think fits them?

well seeing as I have a whole list of songs that would fit them...Here are my top picks
-Give Into Me from Country Strong
-Just a Kiss by Lady Antebellum
-I Do by Colbie Calliat
-One and Only by Adele

I think that the song "Shut up and Kiss me" by Orianthi or the song "Perfect Two" by Auburn are two songs that fit the pair really well but i could seriously chose ten others

Ok lets see
-Perfect Two by Auburn
-Sparks Fly by Taylor Swift
-Jump then Fall by Taylor Swift
-Id Lie by Taylor Swift
-Today was a Fairytale by Taylor Swift
-Your the Reason by Victoria Justice
-Baby I Need You by Kim Taylor
-A Year Without Rain by Selena Gomez
-Stuck in the Moment by Justin Bieber
-Summers Not Hot by Selena Gomez
-Breathe Again by Sara Bareilles
-Crazier by Taylor Swift
Hope I was a help to giving you new Caskett songs! Enjoy! <33 and Caskett Forever

You Had Me At Hello :)By Kenny Chesney

It's as if it's from Beckett's POV

Miranda lambert's gunpowed And lead

Falling slowly - Glen Hansard
or
Can't stop - Mozella.
i think these songs are perfect for them.

lifehouse's everything and fray's look after you
but right now whiskey lullaby by brad paisely and allison krauss it's just heartbreaking for S3

Love Story by Taylor Swift

Always-Bon Jovi

Safe - Westlife

Umm... I would say Winter by Tori Amos mostly from Beckett's POV.
