\'Head Like a Hole\' was a good song, there is no doubt about it. However, it was hardly his best work. The \'Pretty Hate Machine\' cd is filled with great songs, but the two that stand out the most in my mind are \'Something I can Never Have\' and \'RingFinger\'. And as much as I love that cd, it isn\'t his best work, that would almost have to go to \'The Downward Spiral\', though \'Broken\' is damn good itself.
His later work like \'The Fragile\' and \'All That Could Have Been\' are equally good, but don\'t have the same intense feel that the previous work had. Still, I think Trent has influenced a lot of artists and come on, he is just a classic.
