erm eeden
quite hard to answer u tis qns although i wud say the "ah beng"
part u got it quite rite 
though it is not totally the case as
many non ah bengs also listen to the songs and albums
the reason being, in singapore, the word "techno" really means
very very different things to people from different times. actually
it just means the "contemporary electronic music" of the person's
time
i quote some real life examples from the forum. there's this
betametadata who misses his "techno" and his "techno" is the kind
from artist like Technotronic, East 17, Phaga Khan, Londonbeat, 2
Unlimited... which typifies the mainstream electronic music from
1989~1993 (other names for those era oso call "italian house", or
"classic eurodance"). These "techno" would sound different from
FireIce's "techno" which generally sounds like the USURA, Datura,
Cabballero, La Bouche, Reset... which typifies the mainstream
electronic music from 1993~1997 (other names for those era oso call
"eurodance", or "Hi-NRG eurodance"). Then comes the "techno" era of
Aqua, Hit'N'Hide, Daze, SmileDK, Me&My, Tiggy... which typifies
the mainstream electronic music from 1997~2000 (other names for
those era oso call "bubblegum eurodance"). Then comes the "techno"
era of Espresso, Floorfilla, Cassandra, DJ Valium, Fantasy Project,
The Usual Suspects... which typifies the mainstream electronic
music from 2000~2004 (other names for those era oso call
"italodance"). And lastly comes the "techno" era of Cascada, Rob
Mayth, Sven-R-G & Bass-T, Mysterio, Ole Van Dansk... which
typifies the mainstream electronic music from 2004~now (other names
for this era oso call "eurotrance", "eurotechno" or "hands-up").
but still many of the artists of the older "techno" still produces
but not mainstream now
so if we take 1989~1993's "techno" and compare listening to
2004~now "techno" we would be so surprised to find them so
different yet different people still call them the same thing....
HAHAHA... so depending on the person's "contemporary
electronic music" of the person's time
i would happily call the above playlist with a local
term "Feng Tau" techno music so easy to understand lor and for
me i always see the situation and call the electronic music by
whatever name whenever the situation calls for. 
haha heck care la,just enjoy the music.
