http://www.morrmusic.com/">the morr label is good for german electropop. a lot of it is pretty catchy... top picks would be styrofoam, ms. john soda, lali puna. there's streaming song samples on the site; it's all in flash. hell, on my slow loading computer, I think it's the fastest media website I have ever opened.
Múm is also a good one -- icelandic, but not entirely like Björk.. they have childlike voices and it is cute.. sort've like a lot o' jpop :D
Belle & Sebastian works (it's what I started with -- after I finally purchased indie music; not heard.. back in '00)... really, I wouldn't go for their latest though. Tigermilk or Fold Your Hands Child, You Walk Like a Peasant.. those are my favs. on an 'as a whole' level.
Cocteau Twins.. well, they aren't *really* indie.. more like 80s / 90s shoegazer, but they were a good step up from jpop. hell, even Faye Wong (who did a song on an FF sndtrk) covered a C.T. song. they haven't done a bad song ever.
Mice Parade - Obrigado Saudade. o' course, maybe that's too 'hardcore', but it reminded me of japanese stuff and is pretty cool in an experimental way.
http://www.roguewavemusic.com/">Rogue Wave -- sounds like Ben Gibbard (of Death Cab and Postal Service).. nice little catchy songs.

Also, I've gotta say that Mates of State is only good for one or two songs at once; a whole album is gag worthy... sorry to say -- of course, maybe that's not an "unbiased opinion". a friend of mine was going to open for them, but decided not to since their music wasn't the type they wanted to be associated with.

Alright I'm done... I think I'm feeling too longwinded today. I apologise.
