Thanks for explaining @Schoonerguy !
I checked the Pandora account linked to your Community Profile and from what I see, it looks like announcements you heard are messages made by artists or curators on Pandora just thanking you for listening. You have the option of disabling these Artist Messages to prevent them from playing on your account. I've gone ahead and disabled the artist messages for you on my end but I'll leave the steps below so you can disable/enable them whenever you'd like from your end. From your computer:
Click the icon (initial or picture) in the top right corner of the page.
Select Settings, then Content Settings.
Toggle the switch to turn Artist Audio Messages Off, or if you'd like to disable these messages for specific stations, uncheck individual boxes underneath Play Artist Audio Messages.
Hope this helps!
