I know platinum status changed but this seems well dodgy.
The links which should confirm whether all Kylie's albums since 2000 have indeed gone platinum don't go anywhere. Is there another source? I'm not doubtful about her early 00's stuff going platinum but I find it hard to believe both X and Aphrodite have sold over 1 million in the UK to go platinum and I'm pretty sure Body Language didn't. Very few albums even sell that much here.... Unless it can be proved somewhere else I think it looks like a Kylie fan has edited Wiki to make her sales look greater than they are.
Edit. It seems platinum status in the UK was downgraded to 300,000 for albums in 2009. That explains it. I lived in America for several years so get confused with the differences in sale measurements.
However it also confirms only one Madonna album, MDNA, hasn't gone platinum in the UK. All the others have. Hard Candy by rights is platinum under this new rule so should be classed as it.
Platinum in the UK has been 300,000 sales for at least a couple of decades. I remember as a teen in the 90's keeping an eye on the sales figures of Blur, Oasis and Pulp and noticing this.
