The first major artist crossover was by Amy Grant, with her 1985 album "Unguarded" and 1991 hit song "Baby Baby" from the highest-selling Christian album "Heart in Motion". The albums and single were distributed by a Christian label but received heavy play on pop radio stations and were chart-toppers on the Billboard charts. Since then, many artists have been labeled as "crossover artist" regardless of whether they originally intended to market to the Christian market, secular market, or both. The most notable recent Christian crossover artists are Lauren Daigle, Kirk Franklin, Switchfoot, The Afters, Relient K, and many of the artists on Tooth & Nail Records such as MxPx, Underoath, Emery, Lifehouse, Zao, and Dead Poetic.
