The only thing I could think of is that Rdio or any ad-network is sharing information with a 3rd party and that 3rd party pushing the info to Spotify. The other way is through your social network like activity. Did you "like" the band on Rdio?
Why would rdio make this information public? It seems like really valuable information that they are just freely allowing to get scraped
ah ha! this has to be it..
I didn't "like" the band, I just listened to their stuff normally. Since Spotify runs natively, I wonder if they have a way to access browser information
I say spend some time trying to re-create it. Maybe some activity within Spotify itself triggered the email.
Do you have Radio connected to Facebook? It posts stuff you listen to if you do; that could easily explain how Spotify got the information...
I do have Rdio connected to fb, however it isn't posting anything on my fb wall
I wouldn't be surprised at all if they were indeed spying. But it might been pure coincidence. Can anybody from Spotify or Rdio shed some light?
