This explains how an app can be made to automatically backup the app data which may include user preferences, playlists, etc. to the cloud. 

Very few apps implement this feature. On my phone, they are tTorrent and X-Plore. It's awesome when even after reinstallation of the app whether or not after a device reset, the app is in the same condition as it was before. All my preferences then and there and I can directly use it without having to set it up again going through all the settings and stuff. 

 

Poweramp should have it too.
