wont clear cache or saved data even after going through all process

[Tsplitstone]

i have tried three times to clear my cache and saved data just through the setting on the app. then i tried through my phone app settings. then i uninstalled and restarted my phone. all times i log back in to the app and everything is still there. my 14 yr old was using my app and i need it cleaned off now but really dont want to go into 300 songs one by one. PLEASE HELP

Removing the spotify cache will only delete downloaded music. All the other information (playlists and Your Music/Library) is stored on Spotify's servers so it automatically syncs across devices on the same account.

The quickest way to delete stuff you don't want from your library would be to use the desktop client which allows multi-selection.
