Miguel debuted a song called "How Many" about the deaths of Alton Sterling and Philando Castile on his Soundcloud page this morning, singing, "I'm tired of human lives turned into hashtags and prayer hands."

Knowing that his work -- and everyone's work -- preventing the deaths of black Americans is far from over, he noted he intends to continue updating the song.
