B.B.B.F.F.
B.B.B.F.F. (Big Brother Best Friend Forever) is a song that is featured in the episode A Canterlot Wedding - Part 1. Twilight Sparkle first sings it when she explains to her friends that her brother, Shining Armor, was the only pony she trusted as a friend before she was sent to Ponyville. Later in the episode, when she was afraid she had "lost a brother" because of an argument, she sings a somber, much shorter reprise. The song is notable in being Twilight's first solo song. Meghan McCarthy stated that she was inspired by the relationship her daughter has with her older brother.read more
