I think any style of music can be "redeemed" (by that I do not mean slapping "Christian" lyrics onto it) and appropriated by Christian artists. Some styles will be more suitable than others, obviously. And for some Chrisitans, because of their background, listening to ANYTHING of a particular style may be wrong/sin and to be avoided, because it may bring up memeories or incline them to certain past sinful actions or stir the passions.
I listen to alot of instrumental music which takes the whole question of sinful lyrics out of the equasion. But most people like songs with lyrics, so one must be discerning.
I agree with Sabbas that certain types of literature and music will raise the mind back to a humane level (which alot of pop culture lit. and music cannot do) so that the mind can be elevated enough to be worked with, evangelized and converted - very wise insight of Fr. Seraphim.
But I also believe pop music can be redeemed. Although I am not a great fan of hip hop (my college age son listens to it) and think most of the lyrics are disgusting, the form itself is not intrinscially evil. A Christian artist could write lyrics that reflect a postive, godly outlook on life. In N. America, we Orthodox are pretty heavily caucasian, so you probably will not be seeing any Orthodox rappers any time soon, however! [not that whites can't/don't rap, but the CCM rap groups like DC Rap are not coming out of our culture, but rather an evangelical and/or black church culture; the Orthodox Church is thriving in parts of African, however and Orthodox missions in African-American neighborhoods should be on our home mission agendas in my opinion and I think our tradition has alot that would speak naturally to people of color - but that's a subject for another thread]
I am a guitar player and teacher. I don't listen to alot of heavy or speed metal ( I prefer jazz/ blues/ Celtic/ folk and americana; also, Orthodox liturgical music and chant, and to Arvo Part and John Tavener - both Orthodox classical composers) many of them are phenominal, classically-trained guitarists and I admire thier skill. And I have bought a record or two in that genre (at least with a Satriani there are no lyrics to worry about)!
I think it is important to be wise and purposeful. In the morning before prayer, when making my coffee and getting the cobwebs out of my head, I don't want to listen to something that will remove me from that vulnerable openness to God I feel when I wake up so I play nothing or else liturgical music or Arvo Part/John Tavener; maybe an instrumental guitar record of Celtic music. Later in the day I will listen to my other CD's.
St. Romanos Records (www.saintromanosrecords.com
) has CD's by contemporary Orthodox artists . Their Cross Culture Project I and II CD's have a sampling of various Orthodox musicians. The songs range from kids songs to songs about the liturgy to worshipful songs (non-liturgical of course) to songs about saints to songs about Orthodox Christian living to love songs to amusing songs - in short songs about anything in life from an Orthodox world view - what one would expect from Orthodox artists.
So be discerning; be non-judgmental regarding style (again, lyrics are another matter); be honest (and perhaps stern) with yoursellf; and practice variety and the broadening/elevating of one's tastes. I think alot of what St. Paul has to say about eating or refraining from certain foods In ICorinthians ans Romans applies here!
