Well, at this time in my life I seem to prefer music with no words... meditation music with soft, long, slow harmonies, made with long mellow tones. Ahhhh.....
I also listen to LDS music from lds.org, particularly the YW music - http://www.lds.org/cm/display/0,17631,7028-1,00.html, although some of them are specifically LDS, there are others that are just plain uplifting for everyone. For instance, "When Someone Cares" and "Look Inside" (my favourites).
I do have JW song book... I like collecting sacred music....
Do JWs have free mp3 downloads I can access, with words and music?
I also listen to good pop-songs, that have good morals. I don't generally listen to Christian music radio, because I find it mildly blasphemous to hear Jesus' name mentioned so often and in a way that could be flippant or insincere. That's just how I feel about it...
