  == Sales figures ==  Just a note to say that the numbers in the WSJ article is problematic as it includes streams and track equivalent albums, and as can be seen from the figures for the others, it distorts their numbers by quite a bit. Clay Aiken's number is more similar to the older total number because he doesn't sell as many singles and tracks, but that is not true to someone like Kelly Clarkson and Carrie Underwood, adding the numbers will actually make Clay Aiken look like he is selling fewer albums.  We cannot add the number for Clay and not for the others.  Billboard as of now still makes the distinction between number of albums sold and units (the new formulation) sold. It may need discussion first to add the numbers.
