Its not a new problem. I grew up in The Salvation Army and remember reading quote by William Booth saying "Why should the devil have all the good music"? or something like that. And that was in regards to brass bands back in the 1800's.
While I agree that some Worship Bands, look and feel more like rock stars and can feel very "worldly", a lot will depend on the specific location, timing, focus, and heart of the 'worshiper(s)'... I'm not much of a singing/dancing worshiper in public, at the best of times, but will pour my heart out before the Lord in my own way. I might do this while laying down, listening to music, working around the house, or even while driving.
I like older music from Keith Green and Don Fransisco (that's old in my book, and I'm in my 50's) , as well as more modern music like Casting Crowns, Sidewalk Prophets, MercyMe, Chris Tomlin, for King & Country, etc. I'm not really up-to-date with some of the current stuff.
I don't understand some of the words in old hymns (any more than I
like reading the KJV

), but that's just my experience: let the flame wars begin!
Again, to me, it all depends on where your heart is focused as a worshiper. The pendulum can swing too far in both directions.
We are not all the same and I don't think God ever intended us to be like penguins. U N I T Y - does not equal - UNIFORMITY
We should be free to worship, with open hands, a contrite heart and a clear conscience. I am confident the Lord is pleased with such worship.
