wow this is hard.
i think these are my 10 all time-faves of nin right now:
into the void
please
the becoming (still)
even deeper
beside you in time (tie with "the great below")
she's gone away
somewhat damaged
sunspots
ahead of ourselves
demon seed
the minus-songs (songs i can't stand anymore):
head like a hole
god given
survivalism
the hand that feeds
burn
satelite
nearly top 10: everything, the wretched, burning bright, echoplex, your touch, i do not want this, hurt
