that song is called 'My Heart' from Paramore.
Suka banget sama lagu ini dari awal denger, karna di lagu aslinya ada sedikit scream2nya gitu di bagian akhir, liriknya mellow, tapi lagunya sama sekali enggak kedengeran mellow buat gue. Awalnya udah suka sama paramore waktu di Original Soundtraknya Twilight, terus searching2 dapetlah semua lagunya, pas denger lagu ini makin jatuh cinta sama paramore. dan akhirnya cinta mentok! :'D

Here's the Lyric :D

I am finding out that maybe I was wrong
That I've fallen down and I can't do this alone

Stay with me, this is what I need, please?

Sing us a song and we'll sing it back to you
We could sing our own but what would it be without you?

I am nothing now and it's been so long
Since I've heard the sound, the sound of my only hope

This time I will be listening.

Sing us a song and we'll sing it back to you
We could sing our own but what would it be without you?

This heart, it beats, beats for only you
This heart, it beats, beats for only you

This heart, it beats, beats for only you
My heart is yours

This heart, it beats, beats for only you
My heart is yours
(My heart, it beats for you)

This heart, it beats, beats for only you (It beats, beats for only you)
My heart is yours (My heart is yours)

This heart, it beats, beats for only you (Please don't go now, please don't fade away)
My heart, my heart is yours (Please don't go now, please don't fade away)

(Please don't go now, please don't fade away) My heart is yours
(Please don't go now, please don't fade away) My heart is yours
(Please don't go, please don't fade away)
(Please don't go now, please don't fade away) My heart is...
