they did not have pre-orders for the deluxe in US I though so that may have some impact.
Also it has been a while since they released anything big. This album may not do as well in sales but it is still their best work (fantastic).
This is just the perfect kinda pop oriented pop rock. Also just gonna say it since I saw the charts and I know they reflect sales but Kids In The Streets> Some Nights. Both bands are good but this is the difference between a great album and good album. They really should switch places but I guess Kids In The Street does not have a big single sounding song just a album full of memorable ones.
