Spotify has certainly degraded over time. My latest frustration: Controlling external devices via my computer or phone.

I'll often play from my phone and connect it to my Echo speaker group. This used to work so seamlessly - it was beautiful.

But now - it takes 10 seconds for the initial connect. If I hit play/pause there's a 5-second delay to the point where I'll tap it twice, which is also delayed, and then it'll stutter and jump around. And worst of all: I'll hit pause, come back to it in a few minutes, and it's completely disconnected.
