Agree. They don't care about UX at all.
Trivial example: the Home button that doesn't reliably take you home. It's some sort of home/back hybrid where you're never quite sure what it's going to do (this is on iOS). Instead have two buttons: one for Home and one for Back. Then we'd all know what to expect when we pressed one of them. Not difficult, is it?
More substantive example: poor integration, to the point of being dangerous, with Apple Carplay, and a generally crappily optimised, unresponsive and, yes, dangerous experience for driving with or without it. Every time my Apple Carplay connection fails it's due to Spotify. Every. Single. Time. Screw you, Spotify: I couldn't give a damn about Joe Rogan but if you don't fix your poor quality, dangerous user experience I'll cancel, because it's not worth a horrific car accident just to switch to a different playlist.
(Tangentially, since I mentioned Joe Rogan already, I'm unpleased that a bunch of songs have disappeared from my playlists because of Spotify's poor and purely reactive handling of his podcast. I like the fact that he talks to people from a range of viewpoints, many of which I disagree with: I don't like the fact that it took a social media fiasco and a bunch of artists leaving to label and tag his episodes more responsibly. You should have known what you bought when you acquired rights to his podcast: it's called due diligence. You should have had, and implemented, a business integration plan, in place from day one. Who spends $100M+ without doing this? I'm guessing all you saw is subscriber numbers. Stop being lazy.)
I wish I could reincarnate Steve Jobs so he could go and work at Spotify and fire Daniel Ek and Gustav Söderström in an elevator because I honestly can't think of two individuals more deserving of such a fate.
(Btw, I realise the thinking here is likely that if you have the artists maybe the product doesn't matter so much but, as the Rogan incident shows, having the artists isn't guaranteed. You need subscribers onboard too, to ensure that artists are less tempted by other platforms an options, which means the UX needs to be solid. Clearly it's not at the moment.)
