Haven't ads always been recommendations in some roundabout way? Regular ads are technically just a company recommending their own product/service to you (whether you need it or not).
What the shit are you taking about? Musicians literally want to sell you their music. How else are you discovering new music and artists these days? Hoping to stumble upon them?
I would bet that on Spotify most people discover music by listening to personalized generated playlists and not by waiting for ads to guide them. Have you ever used Spotify?
