Contemporary Christian music (or CCM—and occasionally "inspirational music") is a genre of modern popular music which is lyrically focused on matters concerned with the Christian faith. Today, the term is typically used to refer to the Nashville, Tennessee-based pop, rock, and worship Christian music industry, represented by artists such as Avalon, BarlowGirl, Jeremy Camp, Casting Crowns, Steven Curtis Chapman, David Crowder Band, Amy Grant, Natalie Grant, Jars of Clay, MercyMe, Newsboys, Michael W. Smith, Rebecca St. James, Third Day, TobyMac, and a host of others. The industry is represented in Billboard Magazine's "Top Christian Albums" and "Hot Christian Songs" charts, and by Radio & Records magazine's Christian AC (Adult Contemporary), Christian CHR (Contemporary Hit Radio), Christian Rock, and Inspirational (INSPO) airplay charts, as well as the iTunes Store's "Christian & Gospel" genre.
However, not all modern music which lyrically identifies with Christianity is part of the Nashville Contemporary Christian Music industry. Alternative genres such as punk, hardcore, heavy metal, and hip hop groups deal explicitly with issues of faith but are normally not considered CCM. Also, several mainstream artists such as The Byrds, Bob Dylan, Van Morrison, Elvis Presley, Kanye West, Creed, The Fray, Evanescence, Lifehouse, U2, and rapper DMX have dealt with Christian themes in their work but are not part of the CCM industry.
