You do realize that the names next to the tracks are the writers, not the producers.
A raven is a bird, so the song could be a metaphor comparing herself to a raven.
I think it's hilarious how the picture is only supposed to confirm a release date for Crystal's album, and people only assume it's Britney's album above because of the "B. Spears" in the writing credits for the tracks. Spears is actually a common last name. Thousands of names begin with the letter "B." Who knows, maybe "B. Spears" actually means Butch Spears, Belinda Spears, Bubba Spears, Brad Spears, etc. etc. The list goes on. It doesn't have to be a singer, it could just be a random songwriter.
Define "Black", cause I most certainly don't want her to be the Britney she was back in 2007.
Obviously they mean music-wise, her doing Urban-type sounds. "Gimme More", "Break the Ice", "Get Naked", "Freakshow," Blur", "I'm A Slave 4 U", "(I Got That) Boom Boom", etc.
