Some lyrics to see how the song fits:

Everything
And in this crazy life, and through these crazy times
It's you, it's you, You make me sing.
You're every line, you're every word, you're everything.

Together Forever
Together forever and never to part
Together forever we two
And don't you know
I would move heaven and earth
To be together forever with you

Accidentally in Love
Come on, come on
Jump a little higher
Come on, come on
If you feel a little lighter
Come on, come on
We were once upon a time in love
We're accidentally in love

Iris
And I don't want the world to see me
'Cause I don't think that they'd understand
When everything's made to be broken
I just want you to know who I am

Rolling In The Deep
We could have had it all
Rolling in the deep
(Tears are gonna fall, rolling in the deep)
You had my heart inside of your hand
(You're gonna wish you never had met me)
And you played it to the beat
(Tears are gonna fall, rolling in the deep)

The next round is the moment where Puck saw Beth at Shelby's, what song do YOU think suits that scene?

Accidently In Love. They never seemed suited to one another and evreyone thought she'd stay with Artie but they got together and are currently the longest running Glee couple, lets hope they stay together. Tike for the win :D

I thought you couldn't enter a song that was used on the show. Rachel and Jesse sang Rolling in the Deep in epside 2x20 "Prom Queen"

This one

@KusoAkuma; Crap... that is true.
