I'm 20+ as you can see, i hate talking about me but i'm going to give it a go.
Listening to KOL music was like an apocalypse. The first song i listened to was "Sex on fire"(of course cause that's the first KOL video they showed in my country and i was instantly glued to the screen. Then i looked for more of their "stuff" and ever since i am addicted to it. But i dont want to go to rehab. I say NO NO NO!!
I have found a great way of bending and stretching time by listening to their songs on my mp3 player. Waiting for the bus, boring days at the office, depressing sunny days, all that is happy break while i am listening to the Kings.
I love all their songs and i can say that for only very very few artists.
So i'll just say thank you for the music!
