Right on, all those are great! In my dorm we boot up the menu screen to Halo, switch the audio to my speakers, turn it up loud, and open the door- that way we get at least a 4 player game in a couple of minutes
Magus' theme music from Chrono Trigger really got me going, back in the day!
Personally I also like the new UT 2004 Deathmatch music..
