Thanks for following up, @triolop0.
I recommend checking out the accepted solution to this thread if you are running into issues with repetition when shuffling your stations: Music is repetitive in shuffle mode
I will also say that if you do choose to upgrade to Pandora Premium, that will give you the option to create customized playlists where you can pick and choose what songs you want to include in your listening session.
This would also be a good idea if you were hoping for a more on-demand type of listening experience.
You can find more details about Pandora Premium here.
Hope this helps!
