The book The New Age movement and the biblical worldview: conflict and dialogue (1998)‎, written by John P. Newport, includes a presentation of new age music. I quote:

A certain percentage of New Age music is composed with the deliberate design to alter consciousness, or to give the listener a pantheistic mystical experience, or to open up the individual to the influence of demonic spirits. From the biblical perspective, this New Age music can be dangerous

I am just hoping that this percentage is not very high. It sounds dangerous indeed!

But, on the bright side, the book includes a fairly lengthy presentation of our genre that is not all black and white. Read the book on Google.
