Perhaps they define usage based on time?

It seems reasonable that users would spend 1b/80m = 13 times the amount of time listening to music than they do interacting with Facebook.

If you're going to use that metric, use ~1.25 B for Facebook (monthly actives on mobile).

1.25B/80m = ~16 times. The average Facebook user in the US spends about 40 minutes on FB per day (not sure of mobile vs desktop breakdown):

16*40minutes = 10 hours per day on Pandora on average. Absolutely no way.

I'm not sure if "checking facebook" is the same as "interacting with facebook"

That's a pretty shady thing to do.

You think that defining "most used" by "usage" is shady?

If I spend 3 minutes taking a picture to post on Facebook via my iPhone Camera App's integration with Facebook, where does that weigh in?
