So we can't clearly know unless someone claims them to be supported by 63.2% certified sales, I got it now. But let me correct you about this: 1) Your number are lower. Because as Billboard says her sales are higherhttp://www.billboard.com/articles/columns/chart-beat/1569263/ask-billboard-why-do-some-songs-fade-out-and-others-end-cold?page=0%2C3. 2) You hadn't even included What the Hell which sold 2x Platinum in USA. I assert these because Billboard seems to be reliable source. I don't say "check the pages' sources" in vain. Because for example Let Go sold 1,711,088 copies in UK.http://jam.canoe.ca/Music/Artists/Q/Queen/2006/11/17/2391437.html That's why your certified units and mine are different. I know you may not accept it but (and that's why) thanks for your understanding anyway. Music industry can be very confusing as you see. Hope we can add her someday, right? Thanks for that claim requirement thing too
