Fix slow app in case of many libraries and/or offline songs

[wintercounter]

I really have enough of the app being unresponsive too many times even for minutes.... No matter what I do, play, search, browse, the whole app experience is being bullsht. I've seen multiple threads where it was suggested to: "Remove as much things from your library as you can." NO! I DON'T WANT TO REMOVE ANYTHING!!! Fix/optimize your app! You're saying that Spotify is a legal replacement of our old listening habits, but this way it's simply not! My phone will die cuz I have 1000+ songs in my library?! Seriously??? Have you heard WinAMP before? It could handle 1mil songs easily in 1995. I'm having this issue since years now. I even moved to Google Play (no issues there, wow) but got back because of the rest of my family.

Here are some combos I had issues with during the years:

- MotoX 2014, Android 5-6, Internal storage

- HTC 10, Android 6-7-8, Internal/External storage

You can see it's not an issue with my phone or net or my SD or whatsoever. By now it's got really frustrating to use Spotify...

Just as the top of the cake: you're constatly removing signifucant features from the app... Like the ability to play a playlist folder for example (desktop app can do it, wow).

As a developer I always liked Spotify's culture and what it represents amung the developer community, but now I just feel like a bunch of idiots working there. You've got too big and money is being in focus and not your users anymore. (Yes, I'm being personal and it feels fckin good.)

EDIT: Issues coming while being online. If I turn off Wifi/Mobile data while watching the spinner or waiting my (offline) song to play, it instantly starts to work. Please don't do any network realted stuff on the main thread, create a service or some sort of worker for that.

UPDATE: Today I needed 10 minutes to be able to start a song. App was frozen, I was fully offline. OFFLINE!!! IT'S THERE AND THE APP CAN'T PLAY IT!
