Nine Inch Nails - Sin because no places i've been to have played this one (unless it was played in Derby once) & it deserves to be played
Mr Manson - Sweet Dreams because it rocks hard & User Friendly because the lyrics are just so right
Ministry - Jesus Built My Hot Rod, Bad Blood, Just One Fix, Burning Inside or Stigmata (but not NWO as it's comparatively dull)
Skunk Anansie - Charlie Big Potato because it has breakbeats, is dark & filled with tension
Placebo - Every Me Every You though the singles off of Black Market Music were all pretty rocking numbers as well, those being Slave Against the Wage & Special K
Smashing Pumpkins - The Everlasting Gaze because it has a huge riff similar in size to that of Corgan's Celebrity Skin riff
KoRn - Blind because it's a classic, Faget because some of the lyrics are somewhat cathartic & Got the Life because it rocks & has a funky, skippy beat
that'll do. & yes it did take me more than 5 minutes to compile.
