Actually 6xPlat for a 2011 song is FAR worse than 5xPlat for a 2008 song, Digital Sales exploded there in late 2010. You can see how "Umbrella" and many others huge hits are not there, and only massive hits like PF/HnC/SL have barely made it (and with the help of its catalog sales)

2008 highest certified song: 4xPlat Girlfriend. No more songs above 2xPlatinum
2011 highest cerfitied song: 10xPlat Party Rock Anthem. 2 7xPlatinum songs

And I heard the she was only US

How's about E.T, IKAG and LFDN??? they were huge too???

Lol. Just look at tour grosses. Pink will forever be the Queen of Australia.

All of her hits were released in the digital era. That's only why.

So were Gaga's
