i haven't edited my xbox live playlist in a while... normally, it's part majestic instrumental, part loud rock music.  for example, in my old list you can hear "Advent: One-Winged Angel" and then "Blow Me Away."

i'm thinking i'll soon change it to something like this:

A Knife in the Dark (Fellowship of the Ring OST)
Serenity (Serenity OST)
Diva Dance (The Fifth Element OST)
Advent: One-Winged Angel (FF7: Advent Children OST)
The Requiem Overture (Requiem for a Dream OST)
The Diary of Jane (Breaking Benjamin)
So Cold (Breaking Benjamin)
Blow Me Away (Breaking Benjamin)
Cassie (Flyleaf)

and fill in the blanks with maybe some Finger Eleven and some naruto stuff.  that should make for some fun runs in Perfect Dark Zero or (once we get it) Rainbow Six Vegas.
