Behind "Sandcastles"

Interesting story:

"Berry was homeless when the song made its way to Beyonce last year, and uncertain how, or if, “Sandcastles” would be ever be used.

"When someone sings your song, it’s incredible," said Berry. "But when the biggest artist in the world sings your song, it’s really a defining moment for yourself that you know you’re supposed to be doing what you’re doing.”
