People, in general, like to sing. Whether they are very religious or total atheists, most people like music and song. Ask any football supporter. From singing, “Who ate all the pies” to the referee or “You’ll never walk alone” to their mates, fans like singing.
Fans pays hundreds of Rands to hear their favourite musician sing, even wave their cell phones and sing along.
In the morning, you might catch yourself singing in the shower.
Music is an inherent part of every society. All countries have National Anthems that its citizens sing together to create national unity.
Most people like singing. We may not be good at it, but we love it. Since music (and song) is such an important part of life, it should not be surprising that the Bible says much about it. In fact, the longest book in the Bible is a song book—the book of Psalms.
Often, in the Bible, when God has delivered his people, they sing about it.
