There is my favorite Korean singer (CL) :
Oh no nolza... that's shit 
Agreed I hate that piece of human waste, his "music" sucks and I hope he dies.
This is why;

http://kotaku.com/5967074/gangnam-style-rapper-apologizes-for-his-anti-american-past
And everyone forgives or forgets this shit, so suddenly when he became "popular" he's "sorry", lol what a worthless sack of shit.
C'mon Demon. Read the 3rd comment at the site you send:
"What about "free speech"? Do we pick and choose who has the right to speak? Are double standards OK?"
The first comment is even more on-topic:
"Anything performed by Psy can't be any more offensive than some of the lyrics I've heard coming from American "Rap" performers. There are more important issues than this, and it's not the first time America has been demonized by others. Get over it and move on."
lol, I don't want to even think about what they are talking / singing about in some (metal) songs. 
Yeah free speech, exactly.
I never said he cannot say that shit, I just said I hope he dies, so stop misinterpreting what I'm saying.
I can say whatever I want, fuck that piece of shit.
Also typical negative and closed minded view about metal, 80-85% of Metal either has neutral or positive lyrics, a majority of them has complicated and well written lyrics.
Just cause you think is sounds aggressive does not mean it's negative or "evil", lol........
Most of this trash mainstream "music" is all about sex, talking about themselves, money, material objects, beating women, tons of rap "music" that have "fuck white people" "cracker", ect.......
Here is usually most of what I listen to;
"1. Strength In Numbers
As we live in these dark days filled with violence, opposition and hate.
There lies a place of saving grace
Protected in the hearts of the humble
The faithful, the ones who choose the path of resistance to protest
Protect, save, proclaim our lives lived not in vain.
In flesh, in spirit eternal
One love, One truth, One destiny
One love! (one love) one truth! (one truth) one destiny
Arise and be triumphant
No rest until all is fulfilled
Our roots must balance our branches
Be vigilant in truth and love
(in truth and love)
[Chorus:]
There is a strength in numbers we must unite mankind
There is a strength in numbers, our faith lies deep inside
(We!) We struggle, (We) we suffer, (So) so we must come together
(We!) We struggle, (We) we suffer, (but) but we will live forever
Babylon's method of deception
So devious the strong are swayed
(so devious, the strong are swayed)
[Chorus:]
There is a strength in numbers we must unite mankind
There is a strength in numbers, our faith lies deep inside
(We!) We struggle, (We!) we suffer, (So!) so we must come together
(We!) We struggle, (We!) we suffer, (but!) but we will live forever
(One love, one truth)
(One love, one truth)
[Guitar Solo]
One love! (one love) one truth! (one truth) one destiny
(Yeaaaaah)
[Chorus:]
There is a strength in numbers we must unite mankind
There is a strength in numbers, our faith lies deep inside
(We!) We struggle, (We!) we suffer, (So!) so we must come together
(We!) We struggle, (We!) we suffer, (but!) but we will live forever
May the sun shine upon you and bless your inner light
and may you find true peace"
http://www.darklyrics.com/lyrics/timesofgrace/thehymnofabrokenman.html#1"3. I Was Never There
Taking distance Walking one step behind
Like a shadow You´re simple minded and blind
If you are unable To take a stand
Or even understand
Ignorance is bliss Close your eyes
And your innocent
You never saw me I was never there
You never knew me I was never there
One by one My memories become
One by one My memories become
Erased, Undone
Burning bridges Leaving ashes behind
Breaking bonds between Isolating
I´m not running Away
Not even moving Just observing increasing
Absence of light Around me"
