Which pop album remains David Bowie's best-selling album?

Although I still prefer his earlier works , Let's Dance was another part of his ever changing style. This was also an introduction for younger listeners .

I love the US, but way too many of these questions don't even consider life outside the US. Bowie was a massive star outside the US 10 years before this, and the early albums like Hunky Dory, Alladin Sane, Ziggy Stardust etc are among the most influential albums of all time.
