We can sing praises without actually giving glory and praises to God!
“These people honour Me with their lips, but their heart is far from me,” (‭‭Matthew‬ ‭15:8‬ )‭

Our fallen nature, namely the flesh is in enmity with God. ( Romans 8.7) It will never give glory to God, but instead wants all the glory. It always says, “If I wasn’t there, nothing would have worked out”. But the reality is that God could do everything without me. All what is done through me at home, in church or at the work place is just because God used me as an instrument. A pen can never take the glory of the composition of a book! After doing far more than all other apostles, Paul came to the understanding that it is just the grace of God!
“… In fact, I worked harder than all of them – yet not I, but the grace of God with me.” (‭‭1 Corinthians‬ ‭15:10‬ ‭)

This understanding is the true worship. By singing praises to God with this understanding, we can put to death our flesh and we will be more empowered to do even greater tasks. Be a true worshipper and be victorious!
