Aside from STILL getting duplicates. Yesterday, I had a song that was on my 'I don't like this Song' list on it.
Wish that I could show a screenshot, but there's a problem... Discover Weekly is updating twice a week. Now, this isn't a nice, Twice a Week, see different songs at different parts of the week. This is happening literally the day after it should be updating (and has).
Oh and image of the duplicate below. This was taken not long before I made this post.
