Worship is what?!

I hold a role in 2 churches that is usually recognized as "worship leader." The job typically involves leading the congregation a few songs at each meeting. Yet how come this does not get defined at music leader or chief musician. Sure, singing a few songs reflecting on the attributes of God
and us expressing how much we love Him is an act of worship. Yet, I am perplexed why it seems it, worship, ends there. God doesn't just leave the room after we break the silence that typically occurs at the end of the music. Nor am I required to lead individuals in sacrificing their lives to God as Romans 12 speaks of worship.
Historically, worship required sacrifice. In the Old Testament portion of Bible, to worship God involved sacrificing some pure animal and placing it on an altar. Singing, prayers, recitation of God's decrees were also involved. In addition the Old Testament speaks that obedience is better than sacrifice- alluding to what God really desires- that we do his will. Although it is a catch 22 in a way because God decreed these sacrifices.
What I am getting at, however, is worship is not merely a few songs and maybe some goosebumps and exciting emotions. It shows that music is powerful and is a blessed act of worship. Yet, worship must go beyond when the music fades. It is how we should live in obdience to God which thereby honors Him.
So maybe what you think of as worship is dry and dull? Look at how you are being a living sacrifice. Am I becoming more like Christ? Remember Jesus came and only did what the Father was doing which glorified Him.
