prolly In the end, at a friends house, waaaay back in 2001… I was only 8
Papercut when I was watching a video for a movie on YouTube
Mine was What I’ve Done, i’ve heard in Transformers. I remember very well
Mine was Don’t Stay. I was at my friend’s apartment and she said ‘I wanna show you something new, I’m sure you’ll love it’. So she put this song to play and I loved it!
It happened 10 years ago and I’m really glad she did it 
For was a entire DVD: Live in Texas
But I became a fan on concert in Sao Paulo in the same year.
Mine was “In the End.” My brother was watching the music vid on Musica =P but wow, that changed my life =D
I don’t remember exactly, I listen to my 1st LP song 5 years ago… I was sure that my first song was In The End, but my friends told me that I listened to Given Up (and I didn’t like it) but I’m not sure about that. I’m sure that I started listening to Linkin Park after listening to In The End hahahahah ^^
The first song for me was One Step Closer at Walmart when they played music videos, I was 9 at the time.
Mine was numb. I watched the music video on TV.
It was in 2006, but I just started to look for other songs when I met a friend who was (and still is) crazy about them. Some time later I fell in love with the band xD
What I’ve Done…
I’ve heard it on Viva, but i watched more video than I listened to the song. Later when I watched the Transformers-Movies I thought: This music is amazing!
And after this I’ve become a fan 
Well, What I’ve Done was my favorite song to play on guitar hero but I didn’t know it was by them. The day i remember was my dad was listening to 99.3 the fox and they started playing In The End and my dad blasted it and then when I got home I listened to it on YouTube and started listening to other LP songs :3
Mine was Crawling , i remember like it was yesterday … I was with 5 yers old , and i was watching tv and started the clip Crawling , it was ''love at the first heard ‘’ hahaha … and at that moment i knew , Y LOVE THIS BAND … and here i’m … being a soldier for over 9 yers
( sorry for my bad english )
My first LP song I heard was the the Music Video for “Crawling”. I was hooked since! cant believe its been 12 yrs since HT
People are going to think I’m pathetic, but the first Linkin Park song I heard was “What I’ve Done.”
in the end because of my brothers, i was 5 years old …
Numb. Some years later I played it in the Talent Show
Mine was Breaking the Habit, I heard it on the radio, shortly after I asked my friend to borrow his Linkin Park CD, I got Hybrid Theory from him and listened to that on repeat for two years until I finally bought some more of their music.
Mine was Faint. And is still my favorite song of LP.
My first song was Papercut cause my dad bought the album and Papercut was the first song on the album!!!
Wake Me Up Inside with Evanescence was the first song I ever heard from LP…and it was all I needed to hear!
