It's called "Discordant Harmony". Try and find it if you can. Also, at least for now, there's a YouTube channel that has nearly ALL the season7 episodes in hd called "MLP NEWS" and it has the eps separated into parts of 5. Just search for "mlp season 7 episode 1" in the YouTube search tab and it should pop up. Then you can go in order or skip ahead. Just a helpful tip, friend.
