If you are getting ads while listening to your music on Spotify, then this means that you on Free Spotify then on Premium Spotify. If you have Premium, there is a way to double check to make sure that you do have premium, then you shouldn't be getting the ads at all.
To check to make sure you have premium, go to your Account Information by either clicking on your name on the top left corner and "Account" or go to Spotify.com and go to Profile than Account. Once you have gotten to your account information in the Account Overview it states whether you have premium or not.
