Sure, but then British stars are effortlessly successful across Europe (population of way over half a billion) but seem to focus on the USA, which always struck me as odd 'cause it's just one country and seems really limiting as far as career moves go.

To give an example; Joss Stone's spent the last god knows how many years trying to make it big over there to the extent that while her music still filters through to the UK today, nobody talks about her anymore (some of her stuff's being used in adverts on TV at the moment, the James Bond game gig etc) - why go to that length?
