Remembrance Day seems like a good day to play war metal. If I was still deejaying I'd definitely host a war metal show today, probably starting out with Bolt Thrower. There's even a poppy of sorts on the band's website today.
Here are some possible song choices (all from the Bolt Thrower discography):
"When Cannons Fade"
"As the World Burns"
"All that Remains"
and heck, probably the entire ...For Victory record.
And as a counter-point, I might play some Anathema, maybe
"The Silent Enigma"
leading into a moment of actual silence...
