Whenever I thumbs up a song, it gets added to my thumbs up playlist. The reason behind the duplicates, as near as I can tell, is that if I thumbs up a song on one radio, it affects that radio's preferences, and the song is added to my thumbs up playlist. But when I thumbs up that same exact song on a different radio, it affects that radio's preferences, and it gets added to my thumbs up playlist again. I know that songs added to the thumbs up playlist manually will always end up on the bottom, and that if you thumbs up them after they play on a radio, they will be added to the thumbs up playlist again. I also know that some songs were released on more than one album or the same album in a deluxe or clean/explicit release or as a single, or by different artists when the song is a collab. But if it is the same song, in the same album, in the same release, thumbing up that same song in different radios shouldn't add that song to the thumbs up playlist more than once. ... View more

I am also experiencing the same thing. In addition, whenever a song is added to my thumbs up playlist by giving it a thumbs up it appears at the top, yet when I add a song to it manually, the song always appears at the bottom. In addition, I am unable to thumbs up songs without them playing in a Radio first. I do not know whether this is an issue with Pandora, or if it just isn't a feature. Also, (last thing I swear), on Mobile, I am unable to see my Collections, nor my Playlists until after I activate Premium Access. When I go to the Collections thing, all it shows me are my Saved Stations, even though they show up on the Web one. Please advise. Many thanks,                       Alexbeau38 ... View more
