Beethoven's 7th symphony, 2nd movement.
If I was to go out, i'd want to go out in a slow motion sword fight to that piece of music. I've thought long and hard on the subject of my death for a while... not surprising when you consider how I thought I was to "go" originally. The romantic in me always wanted to go out that way. My flair for the dramatic always preferred the idea of pouring red wine down both barrels of a shotgun before firing it mid-drink. My dramatic side usually wins, which was why I ended up screaming Hamlet at the birds behind the fences in hyde park some months back. But I always come back to Beethoven, it's what I always find myself listening to when i'm pulling my head out of my arse. Mozart's lacrimosa when i'm going in, Beethoven's 7th on the way out. It's been that way since I was 13.
Music is powerful, emotionally nothing can effect you like music can. You can associate yourself with it, it can rise any emotion in you, make you ill, make you frantic, make you laugh, make you love, cry, smile, grin and on occasion just plain imagine yourself somewhere else doing something maniacal. Nothing can send you through the extremes of emotion like music can. From hip-hop and dubstep to classical and opera, from hard rock and metal to pop, everyone everywhere has at least one piece of music that causes an emotion in them. To me, I find it quite amazing that it is not used practically in psychological therapy, but then I also find it quite amazing that it hasn't been weaponised somehow...
