The app STILL does not run on the background when all apps are killed.
It would be of great use if it kept running on the background like Deezer and Soundclound do.
It is super annoying to have to load the app again every time you hit the "CLEAR ALL" button and have your music interrupted.
PLEASE, ADD THIS FEATURE ASAP.
I know Spotify has a team more than capable of solving this issue with ease.
