For me, I'm going to make a playlist for the different factions.
For the Resistance (my preferred faction) its going to be a bit more fast paced punk/metal:
My playlist right now has a bit of Red Fang, early Mastodon, Black Label Society, early Lamb of God, a little Hammerfall, and of course some Rage Against the Machine. haha oh AND 3 Inches of Blood!!
For the Security I am gonna go more with classic rock/alternative:
My Security playlist has a LOT of Motorhead, some Black Sabbath/Ozzy, Eagles of Death Metal, Iron Maiden, JOHNNY CASH, Led Zeppelin, and Wolfmother.
just gotta set these up soon. WOO
