As a big listener to doujin music, quite a decent sum of it is from Japan, and that's before accounting video game OSTs and groups like Mass of the Fermenting Dregs, Number Girl, m-flo, Nujabes, the pillows, Novasonic, and Shinichi Osawa. Hell, if we want to get really technical, European music falls under the category as "foreign", so we have to throw in Daft Punk, Super Furry Animals, Supertramp, Radiohead, Aphex Twin, μ-Ziq, Squarepusher, Plaid Ceephax Acid Crew, Brian Eno, The Orb, Boards of Canada, etc. into the mix as well.
In case it wasn't blaringly obvious yet, I listen to large quantities of electronic music.
