I recall that the For You page used to have a section that listed the "Playlists made for you". This section listed the "Your <genre/category> Soundtrack" playlists that Pandora generates and updates weekly. For example "Your Energy Soundtrack", "Your Alternative Soundtrack", etc.
It was nice to have these listed and easily accessible from the For You page. They are still available in "My Collection" --> Playlists, but they are a bit buried now in other stuff.
Not sure why the section was removed from "For You", but would love to see it back.
