No, I understand that they are generally released on Mondays in the UK. My point was that they don't release them PRIOR in the UK.
Even with the release dates being on Mondays, you can't argue with the fact that they are touring much more in the other countries than the US. This lines up with how the careers of Kings Of Leon and The Killers unfolded. Hell, The '59 Sound went to 115 on the UK singles charts.
Their labels might not be pushing them more in other countries but they sure are seeing much more success in those countries. And that's why they are paying more attention to those places. I'm not sure why you find it so hard to believe that TGA is seeing more success in those countries.
This happens all the time.
