Interesting topic, let's see what I can add:
1.Have a song on a compilation cd, Swell Maps "Let's Build a Car". Love it myself, but it could empty the room if you throw it on after everyone's been used to Destiny's Child all night.
2.Just about anything by the Jesus and Mary Chain, but especially Psychocandy at full blast. That'll give your guests headaches before the third track
3.Any Englebert Humperdinck, Richard Harris, or Leo Sayre album will suffice, but no Neil Diamond. People would actually stay longer for his ghastly shite.
4.Preston, Feb 28, 1980-Even those of us who like this show have to admit, it's not for everybody
5.The Cure, Seventeen Seconds-drags any party down real quick (though you shouldn't put Disintergration or Closer on afterwards. You want people to leave, not throw themselves from your roof)
6.Pink Floyd, the Wall-As with Dis and Closer, you want people to leave, not die, so put this on at your own risk. But, if you really can't seem to get rid of the last few guests, put this on at full blast and hide in another room. No one can take this album all the way thru.
Those are my tips......
