Wait do you get ads in Spotify even when you pay?
Some yeah. That guy's list is just skimming a bit too. They don't typically halt playing stuff to play ads though - the ads appear when you interact with the app primarily, like when you pull up search or the like.
They'll occasionally do a big pop-up in the app, when you tap something, like, "tap the screen to listen to this performer you've never expressed interest in" (especially when you first open the app). I don't typically see this more than once a day but it is always jarring. Sometimes it'll be a new feature like the dumb tiktok thing. The only one I really like is the end-of-year-summary, but they could really benefit from giving the graphic artist that makes that some sedatives lol. Originally these ads were rare but they made them harder to push aside, fewer obvious points of interactivity. Also the search page and other screens try to push things when you open them.
