Kate Bush: Hounds of Love (super artsy pop, but wonderfully synthy in that special 80's way)
The Cars: The Cars (should go without saying!)
Cat Power: Sun (Indie-rock's Patron Lady of Sadness finds the light and has fun doing so!)
Crystal Castles: Crystal Castles (either of their self-titles oughtta work for you, synth madness with a punk edge)
Cut Copy: Zonoscope
Grimes: Visions (dreamy and adorable)
M.I.A.: Maya (maybe a little too noisy and unpleasant to fit your criteria, but you might dig a few tracks on it)
M83: Saturdays = Youth and Hurry Up, We're Dreaming
John Maus: We Must Become the Pitiless Censors of Ourselves (if you like Joy Division)
New Order: Low-Life (classic in the genre)
Nine Inch Nails: Pretty Hate Machine (if you don't mind a healthy dose of late 80s/early 90s angst)
Of Montreal: Hissing Fauna, Are You the Destroyer (synthy-art pop with a psych/glam edge)
Roxy Music: Avalon
Yeah Yeah Yeahs: It's Blitz (Dumps the garage-rock of their early days in favor of dance-punk)
