I’m not saying that your friend was in this situation, but the repetitive lyrics in many of these songs can put you in an altered state of consciousness. Reason to be concerned I think
Take a look at ecstatic dancing at Club Mysterio - is this of God?:

huh?
To sum it up, it's a theological blinder: that man's "free will" trumps God's sovereignty, that the Holy Spirit cannot act on the human heart and soul unless (and until) the subject grants God permission first.
Thus, it's not a sovereign God being worshipped. Rather, since it's the unconverted soul that (they believe) can actually control whether God "shows up" or not, said uncoverted soul is placed at the center of worship.
Shhhhhhhhhhhhhhhhhh
it’s ALL SHOW and NO SUBSTANCE
and everyone leaves feeling good about THAT!
