Duffy isn't, it turns out, all that bothered by illegal filesharing:
"Somebody asked me the other day what I thought of illegal downloading, and I thought, 'You know what? I don't care', because I think the majority [doing it] are kids and as they get old and get more income they'll probably buy records. So it's just making music a part of everyone's lives."
Not to mention, of course, that as they get older many of them will make records - given that there's been a pretty solid decade of music flowing online now, and given that file sharing is so prevalent, it's almost inarguable that younger artists whose record companies are trying to protect from file-sharing would have been file-sharers themselves. It was easy for Britney to say it was wrong with a fairly clear conscience - but any popstar in their early 20s is hardly going to be able to take the same line, are they?
None of this, though, actually helps us in making sense of what Duffy means by "the big wheel is round".
