If music without drums, syncopation, or a rock beat is acceptable music, then “Yesterday” by the Beatles would be suitable for a Christian. This song has no drums, syncopation, or rock n roll beat so what’s wrong with it? It doesn’t talk about drugs, illicit behavior, or violence so what’s wrong with it? What’s wrong with it is the source. It was written by God-hating communist devils. Rock n roll music was pioneered by ungodly sinners like Little Richard, a sodomite filthy animal, and Ray Charles, a heroin addict. The source of rock n roll music is ungodly.
