And by the way, Lecrae's latest LP came out the same day as U2's Songs of Innocence. The rapper's release is great too.
Lecrae is Christian. He also talks things other than his faith in his music, including wrestling with materialism and justice for, in Jesus' phrase, "the least of these." His music is infected with Christian sensibilities, to be sure. But he is a great artist, a fact acknowledged by Non-Christian and Christian followers of rap and hip hop music.
