yeah, NIN also started me down the whole "abrasive electronic music" road that eventually led to acid techno.
like many other people, TDS was where i really clicked with NIN. it was actually a bit scary in intensity, and had some of the trippiest ideas i had ever heard in music. who else can make blowing on a straw sound so evil?
i actually think The Fragile is also amazing, but it has the one weakness that runs through much of Reznor's work- borderline cheesy lyrics. i would love to hear an instrumental album in the style of TDS or The Fragile, as the instrumental tunes he's done (especially on The Fragile) have been awesome.
you CAN mix some of his tunes with techno, and the later, evil stuff sounds a bit mental in the mix. i managed to find both TDS and TF on vinyl just for this purpose.
