good music is not about production skills
which is where a lot of techno guys get hung up.
but it's about concept and vision

aphex twin is a good example of this .
sometimes his production is so muddy and grungy but the ideas are what makes you listen
mills too..... dj hells old stuff didn't sound great but it had something in there in fact his new stuff is deliberately lo fi.
it allows the songs to come out so you don't get distracted by productio tricks

i like generic european techno as much as i like a good stand out track
a stand out track tends to dominate things and break up the flow a little which is what makes it memorable too.
but i also like records that are just great to mix.

i would probably say that out of my current playlist of techno tracks
maybe only 1 or 2 would still be worth listening to in 10 years
but that doesn't mean the rest is all crap , it's just music that lives in the present that's all.
