Why aren't we singing worship?

In this video the man talks about how people just don't sing in church anymore. Singing worship takes your whole body. It's something that should be done with your heart and mouth. People now a days have so many devices or screens they expect to do something to them that when they look at the worship leaders at the front it just becomes another screen. So if it doesn't change them inside it's not good enough.
It's so sad to think that people now come to worship instead of just coming and worshipping. Instead of praising Him they are just coming people they think it's right. I have noticed this a lot at my parents church and it is really discouraging as a worship leader. It's something to be praying about and I have been praying about. Praise and worship has become a task instead of a desire and I hope God works in that to change it back.
