My song, right now, is "Fallin for you" by Colbie Callait. I just so identify with it at the moment, but maybe thats just me being a typical teenage gal hankering over a guy.
I don't know but I think I may be fallin' for you
Droppin' so quickly maybe I should keep this to myself
Wait until I know you better
I am tryin' not to tell you but I want to
I'm scared of what you'll say
So I'm hidin' what I'm feelin'
But I'm tired of holdin' this inside my head
I've been spendin' all my time just thinkin' 'bout you
I don't know what to do I think I'm fallin' for you
I've been waitin' all my life and now I found you
I don't know what to do I think I'm fallin' for you
I'm fallin' for you
As I'm standin' here and you hold my hand
Pull me towards you and we start to dance
All around us I see nobody
Here in silence it's just you and me
I am tryin' not to tell you but I want to
I'm scared of what you'll say
So I'm hidin' what I'm feelin'
But I'm tired of holdin' this inside my head
I've been spendin' all my time just thinkin' 'bout you
I don't know what to do I think I'm fallin' for you
I've been waitin' all my life and now I found you
I don't know what to do I think I'm fallin' for you
I'm fallin' for you
Oh I just can't take it my heart is racin'
Emotions keep spinnin' out
I've been spendin' all my time just thinkin' 'bout you
I don't know what to do I think I'm fallin' for you
I've been waitin' all my life and now I found you
I don't know what to do I think I'm fallin' for you
I'm fallin' for you I think I'm fallin' for you
I can't stop thinkin' 'bout it I want you all around me
And now I just can't hide it I think I'm fallin' for you
I can't stop thinkin' 'bout it I want you all around me
And now I just can't hide it I think I'm fallin' for you
I'm fallin' for you oh oh oh no no oh oh oh oh
Oh I'm fallin' for you
ETA: Forever Young by Alphaville is another one i love, as is "Firework" by Katy Perry. I really identify with the latter!
