The Android app is such a complete mess for me

I can't take it anymore. There are so many things wrong. Nothing helps - signing out, restarting the phone, reinstalling the app...

Here is every issue I have:

* Album art never saves, even when I download the whole playlist

* Every time I open a playlist it takes several seconds before its content shows

* Playlists with thousands of songs never show its content

* Music I've uploaded to the iCloud glitches, online and offline

* When I try to put a song in a playlist it keeps adding the same song no matter which one I actually added

* There is no way to get in the Downloader unless something is downloading and still it doesn't even show what's already downloaded from before

* If I don't download a playlist at once, I have to remove the downloaded files and download it again, otherwise it won't download at all

* When I add songs to a playlist that is downloaded, the new songs won't be downloaded

And I didn't even mention missing features like SD card support etc. It just can't be that all of the above is caused by the beta status of the app.
