You may call it Techno but EDM (Electronic Dance Music) encompasses a broad range of sub genres that you might want look into.

I compiled a list of some of the more popular sub genres so hopefully next time when you hear an electronic song you don't just blurt our "Oh, Techno!"
ENJOY!

Important Note before listening: Most EDM tacks last 6-7 mins. This is because EMD tracks are made for DJ's to mix with. The beginnings (and endings) of tracks may sound boring but give them a chance, skip about a min into the song if you want to start hearing the good stuff.

Breaks: Non-quantized back beats with heavy synth use. This is a lesser known genre that is sometimes mistaken for Electrica and may have dubstep breakdowns in each track.
Favorite Tracks:
Everybody by Colombo
Lick the Rainbow by Mord Fustang (Miles Dyson Breackfest Edit)

Deep House: A warmer version of House music mixed with soul music with a consistent back beat.
