Music from the manga "X" of Clamp - "Sadame" (only instrumental...)
U2 - With or Without you
Within Temptation - The Swan Song
Raphael - Funambule (only instrumental...) & "Et dans 150 Ans" & "La Ballade du pauvre"
Thirteen Senses - Into the fire
Roger "15 Grand Slams" Federer
Novak Djokovic | Lleyton Hewitt | Fernando Verdasco
Aventura - Me Extraña
Jarcha - Libertad Sin Ira
Radiohead - Creep
Leona & Edwin Jonkers - Was It Love
Tim Hardin - How Can We Hang On To A Dream
Shakira - The One
Snowy White - Bird Of Paradise
Those songs can make me really sad .
Not specially because of the song itself, some of them, but because of the memories .
Bird Of Paradise was played on the funeral of my cousin, now I cry everytime I hear it ..
