Couldn't agree more. Spotify is one of those products that I sort of almost can't live without but yet it's painful how bad they have become in the last couple of years. Instead of improving the service and customer experience, it only got worse (if I had the chance to straight up use an outdated client from a couple of years ago, I would!).
The fun thing is, my company has jumped on the agile train a while back (nothing wrong with that per se in my opinion), and Spotify was always that cool example "where agile works". Well, no idea what they're doing, but if their KPIs mainly consist of how bad of a UX they get away with, they for sure are very successfully improving their product.
It constantly forgets which episodes of a podcast I've already listened to, or where exactly I've stopped when in the middle of an episode. Their support for downloaded songs at this point seems to be almost non-existent (I stopped using spotify offline quite some time ago as it became too much of an annoyance). If a song I liked is not available anymore but is then available again, I have to like it again. It still can't differentiate between studio and live versions of songs which I would like to filter out (I hope someone corrects me that I'm just too dumb to find the right button). I once got an email that one of the bands I liked released a new album - but it was a band with an identical name (and never heard of before!); apparently, they send out mails by matching band names instead of some unique IDs (no idea how that passed any kind of review; must've been some mashed-together 11-hour release).
... the list could go on and on. The thing is; I really want Spotify to be good, it's what made me stop pirating music, it was just way more convenient. It still is, but it could be so much more, especially given all the cash they're rolling in.
