First one for me was via music video ‘In the End’ on TRL with Carson Daly back in 2000 - I remember it as if it were yesterday
What I’ve Done.[biggrin]
My first song I remember hearing was one step closer and it seems like forever ago! LP have been my absolute #1 favorite band EVER since.
The first Linkin Park song I ever heard was Numb. The song was so amazing that it blew my little mind 
ummm, i think it was Breaking The Habit 
In The End was the first song I heared, and I fell in love with it [heart]! I was in my school gym with a friend and someone called her and her tone phone was In The End, and I asked her about it :3
In The End I guess!! Long time ago! [biggrin]
The first song I heard was Somewhere I Belong on my cousins CD. I loved it and just played it over and over again because the songs on the radio sucked and didn’t like the other songs on the CD.(I was stuck in a car and the CD was not a linkin park cd, it was a bunch of different songs.
plaster
my 1st song wasn’t really a all linkin park song but numb/encore, this song is the song i fell in love with.
Leave Out All The Rest.
Did I reply here XD I forgot so sorry if I already had XD
My first song was “In the end”, I heard it 5 years ago in school XD
Then I realised LP is a great band and started listening to them.
It was “In The End”, 11 Years ago.
I’m not quite sure, but I think it was Forgotten. I actually got HT and Meteora as entire albums, so I listened to everything 
My December, so I guess it could be 2001. I was just 7 and I remember that I was happy every time I heard it on the radio. But I didn’t care about the artist and I almost forgot the song. I remembered after two years when I became a fan. And My December is still my favorite song.
In the End
I think it was in 2004
Leave Out All The Rest or Shadow Of The Day
but it could be possible that I heared Meteora songs before,
because to that time I was 7 years old and I listened the whole day Rock Radio
In 2009 a friend gave me a copy of Twilight, I watched it until the credits and then I heard this wonderful song for the first time… so I rewinded it and listened to it for about 10 times I think… I was 13 and I’m not English so I didn’t understand a word of the song but I was just captive by the melody and the amazing voice of our Chazy.This song was obviously Leave Out All The Rest and thanks to it I started to learn more about this band called Linkin Park and so I literally fell in love… and here I am today always supporting this extraordinary six guys without whom I can’t live
Mine was New Divide, I came to know Linkin Park through Transformers
Crawling was the first song I listened too.
