Thanks for your reply and interest. The duplicates are not listed together on the screen.  You have to scroll up and down through the list to find the dups. As far as I know, there is no way to sort by artist or title within the list.  It seems like there was an original list of a hundred or so, then at some point the original list was duplicated once or maybe twice. I've been deleting dups for at least a year or more from the Thumbs Up list.  But, I tend to not spend too much time on it.  Was going to cancel my membership because of this but didn't do that before it was renewed. Would be nice to use Pandora as advertised instead of being so difficult to correct things like this.Thanks! ...
