What data does Spotify send to advertisers?

[spotify_user_48]

I noticed this link in the footer of Spotify.com: http://info.evidon.com/pub_info/1120?v=1

This makes me think that Spotify is tracking my listening habits and selling them to advertisers. As a paying customer I would like the ability to opt out of ALL tracking.

Thank You

As far as I am aware, those options only effect usage on the Spotify website, not inside the Spotify apps.
