LOS ANGELES (AP) — Prince has recorded a song about the unrest in Baltimore. A Prince spokeswoman says the song is also about “the slew of killings of young black men.” A release date has not been announced. Prince held a “Dance Rally 4 Peace” in Minneapolis on Saturday and asked attendees to wear gray in memory of Freddie Gray. He died after suffering a severe spinal injury while in police custody.
