Popular songs not in order

[superOK]

When you're looking at an artist page, why are the top 10 Popular songs in order by listening counts?

For example, I'm looking at Rihanna's page and her #1 Popular song is "Princess of China" and "Diamonds" is 2nd even though it has 64,771,104 more listeners.

Anybody know how Spotify ranks the top 10 Popular songs?

That's odd - mine shows this...
