That’s annoying. But I think there’s a misconception of “if you pay for something it must be ad free.” There’s goals to get to X revenue. It’s totally reasonable to have that way to get to X to be a blend of subscription fees and some forms of promotional content. Also, I am curious if the record labels have any agreements in place that require Spotify to do occasional promotions to both premium and non premium users in order for the service to have access to their music. I’d be curious to see what the “why am I seeing this?” link says.
