It was Nevermind (What was It Anyway)... I was at a Virgin Megastore and they got those big screens that play music videos all the day... and they played the Nevermind videoclip... I fell in love with the song, searched it on the Internet for a while... then I realised my mother actually got the album
So she gave it to me, and I remember I thought it was very strange (remember that at the time I was a Linkin Park fan...)... It was on August 2004... Then I bought every album of the band in a year
