Spotify's recommendations still leave some room for improvement -- and that's bad for both you and the company's bottom line, since you're not likely to play an irrelevant song or tap on an off-the-mark promo. It might get better before long, however. The streaming music service has bought MightyTV, a startup that revolves around using artificial intelligence and Tinder-like swipes for content recommendations. While the full scope of what the acquisition will mean isn't clear, there will be a strong emphasis on ads. MightyTV founder Brian Adams is becoming Spotify's VP of Technology and will refine the company's ad and marketing tech.
