It seems to be a little known fact that, excluding US sales, BTD was only outsold by Adele's '21' Worldwide in 2012. Talk about a global artist. Obviously this also means that of all the Worldwide top 10 best selling albums in 2012 she had by far the smallest %tage contribution from the US (IIRC something like 14% of total worldwide sales whereas some had as much as 65%).
