Lies, damned lies and Spotify-Facebook statistics

From Spotify today, on discovering the almost tautological “people who use the internet more tend to buy more using the internet”:

We know that Spotify’s users who connect to Facebook listen to more music on a weekly basis. They listen to a wider variety of music—in fact we have more than 400 million playlists created in Spotify now. Because these users are more social, they’re more engaged. Because they’re more engaged, they’re more than twice as likely to pay for music.

Bullshit, Spotify. Absolute, unequivocal, correlation-causation-fallacy bullshit. None of the inferences in this paragraph are built upon any kind of logical foundation.
