There are so many... Hard to choose from.
I will choose the one that I find myself stuck with recently. Ahjumah like me loves such songs.
Leessang: Pursuit of Happiness
After waking up at 3pm, my body is heavy – I did a lot last night
Recorded for 20 hours, haven’t really eaten properly and my insides are burning but
It’s okay, the track turned out well – my passion that I poured out in this tiny space
Soon it will bring me fame and money, as it always has
So I can’t rest, not a day, not a minute – if a great song is produced,
Even if my body wastes away, I don’t care, even if I get a mental disease
If a good track is produced, I don’t care if I go crazy
The legend of this era, the acknowledgement of everyone, the “Big Brother” of music -
These words are far away from me but I scrunch up and write lyrics all night
I open my own door of happiness

On my pursuit of happiness, I flew for a long time
So all the shrunken things can put on a smile
On my pursuit of happiness, I endured for a long time
So that someday, everything will shine

Even if sometimes, everything disappears like the beginning (disappears)
Even if everything of me seems pathetic (someday)

While watching Gil, who appeared on variety programs before me,
My mother was envious and asked “Why don’t you do it with him?”
I still remember her eyes, filled with concern that she might hurt my feelings
I’m over thirty years old but in front of my mother, I’m still a child
Maybe that was the biggest reason why I chose to do variety shows
Now my heart is at rest, people tell me how much I’ve grown
Yes, some people may bash me but my parents are happy, that’s all that matters
What more do I need? I’m always an island outside my house
I won’t forget the pride of my parents and engrave it in my heart
Whenever I go home, I see the shoes I bought them are still new
Please stop saving them up and just wear them, open the door of happiness
This part really made me cry... Gary...

On my pursuit of happiness, I flew for a long time
So all the shrunken things can put on a smile
On my pursuit of happiness, I endured for a long time
So that someday, everything will shine

Even if sometimes, everything disappears like the beginning (disappears)
Even if everything of me seems pathetic (someday)

In this marathon called life, our paths might be different and even if we live insufficiently
We live with the fun of filling it up and though there’s a lof of hardships,
Get to know the taste of enduring it and take one more step
“Why is my life like this?” Those words are just excuses
Don’t give up so easily on this game called life
So when you close your eyes in this world, you can open your last door of happiness without any regrets

On my pursuit of happiness, I flew for a long time
So all the shrunken things can put on a smile
On my pursuit of happiness, I endured for a long time
So that someday, everything will shine
