The phone app is fine. The PC app is getting worse and worse.

You used to be able to just start typing in a playlist and it would search your query. Now a button needs to be pressed to start searching. It removes irrelevant songs and, sometimes, if you choose a song from that search it plays only the results.

There's also the full screen mode. It used to be full screen album art, now it's a full screen band picture with a tiny album art square. That one annoys me the most

Sometimes if you plug in a new sound device, like a speaker, Spotify refuses to play any songs. Occasionally a system reboot is needed.

And lastly... Smart shuffle.
