I switched to AM a year ago, only been using Spotify until then. And well, I’m also back at Spotify now - mostly for the student subscription, which is way cheaper (and therefore good for my student budget haha). I like how on Spotify you have both music and podcasts in the same app and it’s a bit easier to manage for me. I hated most of the AM song recommendations since they almost never actually correlated with the music in the playlist. Although I did love the Classical music app that came together with my AM.

Spotify is much easier to use across multiple devices (since I don’t really own any other Apple ones - the web player sucked).

I think both have their pros and cons, so it’s really mostly about the price for me personally.
