I just think it's crazy how long patched Spotify versions have been around for and Spotify has never reworked anything to be able to stop it. They have banned accounts in the past but you can easily backup your entire Spotify profile and restore it on another throwaway or simply make another account that you follow and will always have those playlists you make ready to prepare for a possible ban. You can do anything that Premium users can besides download for offline and it's fantastic. YouTube Vanced is pretty great too for no ads and background playback. Before anyone asks, links aren't allowed here but you will find trustworthy patched versions if you look for the Mobilism forum. It's just the annoying ad-filled download links you need to be wary of when navigating.
