The Stella Sisters got way more than their share of musical talent. Her older sister has the more current record as of this writing, but Maisy Stella has multiinstrumental and vocal talent in spades.
This was the younger Stella's debut single, her take on the theme for the Dreamworks series Spirit Riding Free. It is an uplifting, happy song, and her youthful voice (she was 13 when it was recorded) is perfect for the feeling the song is trying to convey.
I know it's technically a cover - she took over the existing theme song in season 3 of the show - but it's here. Don't @ me.
