i would say something about the wrone usage of the word techno, but... naah. seeing your enthusiasm in music collecting is enough for me. ^v^

Why would be the wrong usage. Oh. 

well, technically, The Prodigy and The Chemical Brother's music isn't really techno. there's a common misconception about the usage of the word techno to mislabel certain genres of music. techno is, nowadays, a really niche genre of electronic music that had its roots in Detroit. it never got huge public fame like house and trance has, but the word is so commonly used for some reason.

During the 90s anything was seen as techno however.  Especially in my neighborhood who had 90% of its populace listening to Rap instead of anything else.

Wasn't very common back then to be called anything else even by radio stations to be honest.

that is true. there was a lot of "techno" compilations, which honestly was for the most part something completely different. there WERE actual techno compilations, however, but they were mostly acid-techno ones and, i think, not as wide-spread and mainstream as the more contemporary "techno" compilations.
