DxG song?

Personally, I think all of the above songs work. But I would add "Firework" or "Teenage Dream" by Katy Perry. Maybe even "DJ got us fallin' in love again" by Usher too.

Well the official DxG song seems to be "You Belong With Me" by Taylor Swift but I honestly prefer "So Close" from the movie Enchanted.

The Main Song Should Be "Sometimes Love Just Ain't Enough" By Patty Smyth And Don Henley And For Another Song I Would Say "Listen To Your Heart" By Roxette.

I think the 2 best songs for the couple are "Just The Way You Are" by Bruno Mars and "You Belong With Me" by Taylor Swift, because Duncan and Gwen like each other for the way they are and Gwen's interests are the same as Duncan interests.

"You Belong WIth Me" by Taylor Swift because Gwen started to fall for Duncan when he was still with Courtney
"Situations" by Escape The Fate listen to this song, you'll get why
"Those Nights" by Skillet because it shows us how they would sneak out to their secret spot, away from everyone else, away from the drama.
"Things I'll never say" Avril Lavigne because they kept oon denying their obvious love one for another during the whole TDA and beginning of TDWT
"Naked" Avril Lavigne because it shows how they know each other's secrets. They can't hide anything from each other
"Sk8er boi" Avril Lavigne it shows the whole CxDxG triangle
"One of those girls" Avril Lavigne again, CxDxG
"Hey Stephen" Taylor Swift because Duncan has many fangirls/girls who have crush on him, and Gwen, is one of them.
"One thing" One Direction Gwen just has this one thing that made Duncan fell for her
That's all...for now
