It's a song titled 'Officially Missing You'..

When I view this blog, what song come up first? yup, its "Officially Missing You" by Akdong Musician. Well, it's originally Tamia's song, but I knew this song when Geeks and Soyu made a cover of it. Then, Akdong Musician sang it too on Kpop Star, and woow it was really good. They made a really daebak cover of this song. Lee Soohyun voice really match with the song,  the accoustic gitar made it more and more beautiful and nice to listen to.

This is the photo of them if you perhaps don't know who Akdong Musician is.

From left to right, Lee Chan Hyuk and Lee Soo Hyun

Wel, well, their family name is the same. Of course! they're siblings. heheh. Lee Soohyun is the main vocalist of the team, while Lee Chanhyuk is the composer and lyricist and also guitarist of Akdong Musician. His style of composing song is really different from other, at least that's what I think since his songs are always easy listening song with good lyrics. And for their profile, you can refer to wikipedia, here is the link http://en.wikipedia.org/wiki/Akdong_Musician

Among all their song, I like Officially Missing You the most.

English Translation

One by one, they left my side
And we’ll probably meet someone new
Oh please tell me why’d you have to go
Cause this pain I feel it won’t go away

I thought I wouldn’t be sad at all but traces of you still remain
At memories of us laughing and crying together, 
Today I’m officially missing you

Ooh can’t nobody do it like you
Said every little thing you do
Hey baby, said it stays on my mind
And I-I’m officially missing you
I’m officially missing you

All the past memories – since the summer to the now cold today,
We all dreamed of one wish together
Since we had the same path, our hearts grew deeper for each other
Even if things didn’t go well, we peacefully fell asleep at night
The lonely air is chasing out the warmth that once filled the rooms
Along with the scent of the songs that we all gathered and sang together
Yeah I’m officially missing them, I’m officially missing you

Well I thought I could just get over you 
(your name tag is still on the door)
But I see that’s something I just can’t do 
(the music signs are still drawn on the practice sheets)
For now, you have left with sadness but someday, 
I hope you will rise again with that one dream

All I hear is raindrops falling on the rooftop
Oh baby tell me why’d you have to go
‘Cause this pain I feel it won’t go away, 
And today...

Ooh can’t nobody do it like you
Said every little thing you do
Hey baby, said it stays on my mind
And I’m officially missing you

Ooh can’t nobody do it like you
Said every little thing you do
Hey baby, said it stays on my mind
And I’m officially

One by one, they left my side
And we’ll probably meet someone new…


good lyrics right? and I.. really like this part the most.

"All I hear is raindrops falling on the rooftop
Oh baby tell me why’d you have to go
‘Cause this pain I feel it won’t go away, 
And today..."
