I think the free version basically removed the ability to pick the exact song you want to play,there was a headline on here a couple days ago like "Spotify reinvents the radio" but in general Redditor fashion, I didn't read past the headline.

I saw an ad for an artist I like having a concert nearby at the top of my homepage. Relevant, but still an ad as a premium subscriber. I see ads when artists release a new album too sometimes, but they usually tend to be pretty good. Smart Shuffle could become ads in music form since I'll bet they were paid to put at least some of those specific songs there. It's annoying that smart shuffle isn't a separate button from normal shuffle too. They also raised their prices a bit.

It's really not bad yet, but all of these recent changes combined is a sign that enshitification is coming. But it does seem like they are being careful about it and not destroying the core of their product for momentary greed.
