What "type" of Jpop, though??? Everyone's (by everyone, I mean Western people who haven't been to Japan) refer to pretty much any song sung in Japanese as JPop, and therefore attaches a stigma to it under the "pop" genre...
For me, good music has no language barrier

I enjoy Acidman just as much as I would enjoy the Butterfly Effect... It's just a shame that it's so hard for non-English bands to break through to Western society
PAL zones for games try to do their part by adding foreign songs to their track list, but really most of the good stuff won't get on there, because it's not "commercial" enough... Which is sad, because I would love to see what France's answer to gangsta rap would be
EDIT: I youtubed it... I didn't like the result

But then again, not a big fan of rap in the first place I guess
