Well, I like every form of music, some more than others. I really wish you could hear Scriabin's Sonata No. 5, Op. 53 for piano. It only took him six days to write. Richter thought it was the most difficult piece in the entire piano repertoire. It was written with some relationship to his orchestral work, Poem of Ecstasy, Op. 54. (You should enjoy it before you try to sort out what is about.)
I could never see why amplified guitars were supposed to be more "holy" than acoustic. Some of the music I imagine someday composing really ought to have back masking that says wonderful and worshipful things of light and life. It isn't styles of music that are wrong. It is the lyrics that must be judged and, to a certain extent, the musicians lifestyles. The waltz was scandolous when it first came out. It was the first popular dance where the couples held their bodies against each other. ("If I said you have a beautiful body would you hold it against me?" -- Groucho Marks) Some of the old standard operas have licentuous lyrics. Much of Country music advocates adultery and alcoholism. Yet that is a sort of default Christian music style in much of the USA.
I've been to "Christian" concerts of about every kind of music. Some is more prominent in the L.A. area, for example, where there is a greater market to sustain it. The anointing can be on musicians lives regardless of the style, and it is ministered as they perform. It is poorly done music that Christians should generally decry. It is a shame we are so impoverished musically. It can be a great tool to reach people with the truth. People will sing revelation of the truth that they would never sit under the teaching of. I think the greatest music is yet to be created. It will be music to the glory of God. I've gotten to the place I just don't hear what I want in hardly any of it. A lot of it is just too much "clangbangconflangerie." Maybe waiting on God I can receive some of what is lacking. What music ministers "peace that passes understanding?"
