Those are good conclusions. But for me, I think it is because of our tradition called "hele or Memeh?" or lullaby. I know that we are not the only race who's doing this, but we can also conclude that since it is part of our culture for a mother to stay with us during our infant stage or be a full-time mom in other words; we are more likely used to in hearing more lullabies during that period. A study shows that singing a lullaby to an infant encourage their development of speech and singing. Another possible reason is the karaoke craze in our country that no one can escape especially during the weekend LOL. I am surprised to learn though that this amazing thing is not really being invented by a Filipino but a Japanese instead? Daisuke Inoue is his name if you google it. Nice post keep it coming :)
