I am a paid Spotify user for almost a year now. I use the web-based app https://open.spotify.com/ on my laptop and Android app on Samsung A6+ phone.

Web based App: https://open.spotify.com/ - The songs stops playing automatically often. I am talking about 2-3 times in an hour.

Android App: - Downlaoded songs simply doesn't work. Everytime I launch the app, it starts to download the songs again and it never stores it. - Even if I somehow manage to get the download working (by repeatedly trying), on being offline it ask me for login. I mean how can I login if I doesn't even have the internet. That's the whole point of being offline.

Sorry for the rant but will be great if someone can help me find out an alternative.
