Author and former rock star Nick Costello claims,”Too many Christian adolescents today are compromising their godly values in favor of opening up their hearts and lives to the devil, fellowshipping with him through secular music that espouses ungodliness and evil. Therein lies the danger; teens are unaware when they listen to music representative of Satan’s kingdom that they’re giving him the honor, glory, and worship he’s always desired.” Excellent teaching tool for parents and youth leaders. More than just another book on music and lyrics. A MUST read for every Christian teenager.
