@Cheflace08 Unfortunately, there isn't a way to remove that listening history on your account if you had an unauthorized user accessing it.
This being said, I'd be happy to help take some measures to prevent them from using your account again moving forward.
This would entail me removing all devices associated with your account.
This would then require you to log back into your account and reset your password.
Let me know if you'd like to proceed with this.
Thanks for getting back to us, @Cheflace08.
I've gone ahead and removed all the devices associated with your account. This will automatically sign you out everywhere including any devices you currently have, so you will need to sign back in once this change takes effect. Please be patient as this may not happen instantaneously.
I also recommend changing your password to something new and not easily guessed.
Click here to request a password reset and make sure to enter the email address associated with the Pandora account you'd like to access.
Hope this helps! 🎧
