Usually we don't report on sound issues in episodes since they are often fixed quickly. However, this time we make an exception since an early unofficial re-upload of the episode that contains a sound glitch appeared on the internet. This version has spread widely already, the glitch even appearing in a few song remixes. So we decided to give you all a quick heads up.The glitch appears in the final song of the episode and sounds like some sort of chat notification went off when Applejack is pulled up the stage by Rara.All the official versions (Discovery Family airing, Hasbro's YouTube channel, Google Play/iTunes version etc.) do not contain the sound bug.In other words, use the official version if possible and stop remixing chat messages into your songs!
