We already knew Sia was participating the upcoming MLP flick as Pony pop star Songbird Serenade, so it would only make sense that she release a big song for the movie. The music video for “Rainbow,” debuting exclusively above, is directed by Daniel Askill and features another impressive performance by 14-year-old Ziegler.
Cut between footage of Songbird Serenade performing for a packed crowd — which of course includes Twilight Sparkle, Rainbow Dash, and the rest of the Mane 6 — Ziegler dances on a stage of water, successfully battling and conquering the elements. As she smiles (yes, she’s smiling in this one!) and twirls, don’t miss the heart-shaped cutie marks on her cheek to match those on the animated Songbird Serenade.
Additional tracks on the My Little Pony: The Movie soundtrack feature Rachel Platten, DNCE, and more, as well as songs performed by the film’s voice actors, including Taye Diggs, Zoe Saldana, Kristin Chenoweth, and Emily Blunt.
My Little Pony: The Movie arrives in theaters on Oct. 6. The soundtrack will be released on Sept. 22 and is available for pre-order today.
