I've switched to Google Music. Although that has its own set of problems, I find it has better (or more dynamic) machine learning implemented for playlists and discovery mechanics. You can even reset the information it has learned from, and start over if you wish. Making Google listen to change-requests (in one of their not-so-prioritized) products will of course not be likely either.
I'd definitely consider switching. Do you happen to know: Are the libraries similar in size/breadth? How is the mobile app support? Would I be able to move my (many many) playlists across services somehow? I think in our software ecosystem it's just a game of "who is doing the most like what I want at the moment." Communication with customers is largely dead.
The mobile app for android is good, but I haven't seen it receive many updates this last year. It seems like it is pushed a lot stronger in the US. They even give you Youtube Red (the no-ads/music/support creators-thing) with the same subscription. [1]
I liked that they allow storage of up to 20 000 of your local songs (if you still have those), integrated into your online library.
I used a fan-made application to recreate my playlists from spotify, but it required that I was a premium member on both services at once, and just directly used my credentials. Most playlists were kinda butchered. I don't have a good migration-strategy to recommend, I'm afraid.
EDIT: Downsides: It does not have an official desktop-app, you have to use the browser.
Does not have official support for last.fm
