- Greetings, Alfons! I like your character very much, you seen the Alfons Åberg TV series, right?
As far as I've followed the scandi "scene",
Swedish synth music seems a bit derivative and "indie"-goofy (fluffy, whimsical noodling), or else it's 80's synthcore survivors with a more goth/EBM sound... Many mainstream bands have incorporated "electronica"- style production into their sound, but without really adding anything to their quality

Depeche Mode and Kraftwerk looks big in certain circles.
Norwegian scene have some ex-metal bands expanding their sound into synth territorium, among these there's some very good bands like Arcturus (which is kind of proggy synth-metal), and Ulver (in parts inspired by post-goth/Coil stuff but without the brilliance, some of their soundtrack work is well worth checking out).
Some is boring "experimentally produced" pop with female vocals, also see: pop stars, mainstream pop with electronic gloss
Denmark seems to have more affinities with the German scene, much glitch/MBV shoegazing post-electronica like Efterklang...
Finnish bands are weird, original, impossible to categorise... Digi-dub and the whole Sahko scene, then there's more recent stuff in all genres, much of it perhaps overlap with the recent psychedelic/D.I.Y. experimental mini-label thing...
Iceland I don't know much about (and they're Nordic, not Scandinavian anyway), are there any great labels/bands out there? Would love to hear about it
The Swedish, Icelandic and Danish bands- to my ears- sound more "commercial" than the Finnish/Norw bands.
