World music gets almost no play in North America. Here in Canada, the Canadian Broadcasting Co. has about an hour on Sunday, and CKUA has three hours of music from Ireland and Scotland on Friday evenings (both on the internet).
"Believe," I have heard, and I have most Wolfe Tones cds, but agree that few people outside of Irish nationalists listen to them. Surprised that Amazing Grace didn't make the list; it is difficult to get away from.
The BBC Radio Three is on the internet, and I often have it in the background as I use the computer. I see that the article is from Radio One, which I don't think is on the internet.
