Automatic backup of songs/playlist using google accounts

Problem Description

I really love the app, but I find it really annoying to have to create a manual backup everytime you add a song to your playlist just to avoid losing your "progress".

Proposed Solution

That's why I think it would be a good idea to implement, like other apps, a login method where you can use your Google account. The app would then use that account to automatically back up your playlists, keeping all the songs you've added intact. This way, the songs in your playlists won't be lost if you haven't manually backed them up, which I think would be much more convenient when using the app. I've attached an example of how it could work.

Alternative Solutions

Automatically back up songs/playlist/more using a google account as storage for the backups

Additional Context

No response

No files, tests, or entry points are identified in the issue. Start by locating the app's account/authentication and manual backup flows, then determine how Google-account storage would fit them; done means playlists are automatically backed up and restored without manual backups.
