I see no problem with modern worship music.
I'm a worshipper and God is the giver of talents,
if he blesses John with the ability to play the electric guitar and susan the drums, and they both choose to use their musical talent to praise God, who am I to say it's not acceptable.
There was instruments back then.
1 Samuel 10:5 (KJV)

1 Chronicles 16 1-7

7 On that day David first delivered this psalm into the hand of Asaph and his brethren, to thank the LORD:
Some might argue, those instruments are different from the modern ones. But as time goes by things are updated, long ago the disciples travelled by foot to share the gospel, Does this mean we should give up modern day technology because it was not around OT or NT times ?
If the music or the message does not line up with the bible..then you have a problem.
Are you talking about Music ( instruments ) or the singers ?
