Electronic love songs must have two qualities to be a good category fit: a significant portion of the instrumentation is electronic, and it is discernibly a love song.
The song can be happy/sweet or sad/bitter, fast-paced or slow (I tend to slightly favor sad/bitter over happy/sweet and fast-paced over slow, so go nuts with that). It does NOT need to be EDM or something like that -- most of The Cure or New Order's oeuvre, for example, would qualify as electronic for this category even though they both have a large rock component. A band with two guitars, drums, and keyboards is perfectly fine here as long as the keyboards play a significant role. The song can be dance-y, synth-y, electroclash-y, poppy, rocky, whatever...I don't tend to like ballads or really ornate, soundscape-y arrangements, so pick those at your peril.
And I don't like most rap.
