They're definitely an instrumental and lyric-based band, as many of their songs have a lot wonderful stories in them. Personal favorites are "K" and "Laughmaker."
In their latest single, I believe, they had a bonus (secret) track titled the Three Old Men, figured I'd translate it for some people that might enjoy it :D It's a rough translation, so don't kill me :x It's so ridiculous, yet catchy <3
A long time ago
Three famous old men
Went on a long, long journey
One was wise
One was strong
One was... quick
The old men
Gathered their respective strengths
And sailed across the rough, churning great sea
One built the ship
One rowed the ship
One was... quick
The wise old man
Beckoned the two to Paradise
The strong old man
Vowed he would protect the two
The quick old man
Quickly looked reciprocally at the two
At the fearless three
The ocean became enraged
And threw at them mountainous waves
One read the wind
One worked the rudder
One was... quick
Struck by the waves
The ship broke down
The three old men
Were thrown into the dark sea
One stayed calm
One became enraged
One... quickly
The wise old man
Began swimming back where he came
The strong old man
Challenged the sea
And dove quite deep
The quick old man
Finding a piece of the ship...
Clung for his dear life
The old men, crying that they would not see each other again
Tried their best to survive
And amidst this, the sun watched
One read the waves
One struggled against water
One was... quick
A long time ago
Three famous old men
Came upon a miracle
One was wise
One was strong
One was... quick
The wise old man
Transformed and became a fish
The strong old man
Won against the sea and became an island
The quick old man
Fortunately, toward the shore
Was shot (was shot)
And the fish old man
Eventually became a bird
And then evolved into a human
The island old man
After a long journey
Became a continent
The quick old man
Ran and ran
And became a cheetah
The human old man
Founded a kingdom
And gave birth to a culture
On the other hand
The continent old man
If you look at it from afar
Is actually moving
And the cheetah old man
Desired speed
And bought a Harley
The Harley old man
Enamored with his hobby
Became a racer
The racer old man
Kept running
And became a cheetah
His face became like that of a cheetah
