Discover Weekly is the one of the best features I've seen from Spotify since I've been a subscriber: I've been finding so many great new tracks. One minor issue I've found is that I occasionally get recommendations in the playlists that I've already gotten in previous weaks (specifically, I know for a fact I've been recommended Leonard Cohen's 'Chelsea Hotel #2 more than once).
It should fairly simple to implement a check to confirm that the song hasn't been recommended previously, or at least a check to make sure the user listened to it.
