The Fine Print: Celine Dion debuted at #1 in February 1998 with "My Heart Will Go On (Love Theme From ‘Titanic')" and did it again that December with "I'm Your Angel" (with R. Kelly). But Billboard doesn't count the second hit as an official #1 debut. Let me explain: The song bowed at #1 the same week that the magazine changed its chart methodology to allow non-singles to enter the chart. Silvio Pietroluongo, the magazine's Director of Charts, explains, "That debuted at No. 1 due to the change in chart rules, not on a proper week to week comparison. The song was ranked in the prior week's test chart." (Billboard is right to be scrupulous about its chart standards, though I'm pretty sure that Dion's small army of devoted fans won't be happy with this.)

I am too lazy ATM and I'm studying, but all I have to say is - Back in 2007-08, 3x & 2x platinum were remarkable achievement. Ofcourse, because of the rapidly growing digital age, it isn't anymore. Rihanna's sales back then were very high compared to that time, and her totals were too.
