I often hear my friends talking shit about the spotify desktop app and web app not working properly. I don't use spotify but it seems like something's not working at least every month or two.
I got so sick of Spotify randomly taking up 100% of a core that I switched to Apple Music. Yes, I actually found iTunes to be more stable…
I once random lost my complete library. Above that, there was no way to get it back. Spotify people however did recover my playlist. I do use Linux client though, which is not officially supported.
Spotify has been nearly unusable for me ever since Spotify moved to Chromium Embedded.
Something is wrong when I have to wait several seconds so scroll further down a list of song names.
I have to quit the Mac app a few times a week, when it just decides it isn't going to play songs.
