Perhaps there is less competition? While we (most Swedes) might be fluent, and actually really really good, I would also assume that it takes a lot to get over the last hump (the accent) which I honestly haven't heard many Swedes do. I think it is a fair argument on its own, but I would assume that the vast majority of Swedish singers actually sing in their native tongue (with the same going for any country). In addition, I also have the feeling that many don't actually care enough to become worldwide stars.
