Flesh is the fever is better IMO. One night in NYC was a 'shock' style tune with did inspire quite a few other tunes but I would say it was a really good tune. It has become dated, good techno tunes are usually ageless.
What is the era we're talking about here? 1990 to 2000? Thats a big chunk of time. Whoever said magneze is on the money for me.
Heres some that I'd say were classic but you can still play today:

YouTube - Umek - Gatex [HQ]
YouTube - House of God - DHS
