Röyksopp is a good Norwegian band, as well as the Kings of Convenience. Royksopp is electroish more while KOC is more indie folk. They are both great bands though from Norway, and they mostly sing in English.

Otherwise Spanish bands like the Gipsy Kings and Buena Vista Social Club. BVSC do great Spanish-influenced covers of popular songs (like Clocks by Coldplay) but they have some original stuff thats great too. Gipsy Kings are fantastic though. All their music sounds so exotic and fun
Italian music is great too, but theres no English speaing songs, unlike the Norwegian bands. Try Fabrizio De Andre, Rino Gaetano and Eros Ramazotti for great Italian music. Eros sounds nasal as but his early stuff is very good.
