Anecdotally, I had to cancel spotify due to shitty experience. One of their app updates on my phone left it completely draining my battery in a few hours even when not using the app, with no way to keep it from running in the background other than to uninstall. (ok or possibly rooting my phone to install more recent android with better background process control)

I pay for Spotify but I don't see it's poor UI/UX problems. The sections make sense, the color contrast is good, browsing through an artists albums and songs makes sense, the playback functions bind perfectly to the media buttons on my physical keyboard. What else could I want?
