Frou Frou has a slightly electronic sound. I reccomend "must be dreaming" and "let go"
Groove coverage-
"moonlight shadow" and "million tears"
Hellogoodbye has an awesome song called "Here in your arms"
Milk Inc-
"oceans apart" and "living a lie"
OH and you have probably heard it in the pepsie commercials but "streamline" by Newton is great!
The Postal Service also isn't necessarily a techno band but they have an electronic sound and "the distric sleeps alone tonight" and "such great heights" are great songs!
Oh and you might like ShinyToyGuns the songs I reccomend are "Starts with one" and "rainy monday"
OH and I can't forget Susumu hirasawa... Just look him up because he is a musical GENIUS!
I will end with Young love. Also not a techno band but they do electronic rock and they are really good. I reccomend the songs "discotech" and "new way to dance"
