I just realized someone had hacked into my account, since apparently a few months ago. Probably because I reused an old password (my mistake). I've now changed my password and used the "log out everywhere" button, so I assume I'll be safe from now on.
But now my account's history and playlists are full of **bleep** from that person. Is there a way to completely wipe out all history and playlists from my account so I can restart from scratch? Thank you.
