I am among the first to admit that certain rhythms, sounds, beats, etc., have various affects: everything from soothing to energizing. (After all, the very word "lullabye" suggests the comforting presence of a mother.)
However, I don't believe that a rhythm is other than that, and if my brain (all our brains) are made in such a way that they respond to such rhythms, then I look at the creator of my brain who made it in such a way.
As with anything else, it is HOW I use this knowledge that determines whether or not it is glorifying of God or not.
I agree. Music and rhythm are tools, and as such are amoral in and of themselves. The use determines the morality or lack thereof, not the genre itself. The person wielding the tool can use it for good or for evil. A hammer can be used to build, or to kill. A gun can be used to feed a family, or to murder a person. If we outlaw guns, we need to outlaw hammers and screwdrivers too, and cars, and airplanes, and power saws, and electricity, because they can all kill. Even a guitar could kill someone, if it's used in the wrong way....
To believe otherwise is to conclude that raising one's blood pressure over 110/70 must be inherently evil.
