Is It Problematic for a DJ to Play Songs That Are Contrary to His Christian Values?

Questions about whether it’s problematic for a DJ on a secular radio station to play songs with lyrics that are contrary to his Christian values, and what approach a musician should take toward royalties he’s still receiving from music that had less-than-Christian lyrics.   As a DJ on a secular radio station that plays music from the ’60s through the ’90s, is it problematic for me to play music with lyrics that are contrary to my Christian values? What approach should I take toward the monetary royalties I still collect from music that had less-than-Christian imagery and lyrics?
