French popular music unknown in western Canada, but pretty well known in Quebec. About 5 TV channels in French plus the French CBC on radio, but only listened to by the small French enclaves.
I seek out a couple of programs, but I don't know anyone else who does.

Why should the BBC give it time? Who would listen? More apt would be music from the Asian continent, or the Caribbean.

Face it, English-speaking peoples, like the Japanese, know little of popular cultures outside of their own.
