I personally think Christians get far too hung up on music. Someone mentioned Ray doesn't like certain types of music. I read an email of his recently to a young lady enquiring about her taste in music. Ray said something along the lines of "You will wonder one day why you thought it to be entertainment". I think its fair to say Ray may well have made that statement regardless of his faith. Some people just don't like certain kinds of music, whether they happen to be Christians or not.
I think what we as Christians need to make a choice about is whether the lyrical content of a song, regardless of genre, is something we should be listening to. I listen to a lot of blues music that has no lyrical content at all, and its wonderful. I listen to a lot of instrumental rock music, its wonderful. My wife listens to a lot of club style dance music that has no lyrics in it, and frankly I hate it. It has nothing to with any possible offensive lyrics, its just the sound and arrangement is offensive to my ear.
When I was in Church I listened to a lot of Christian "worship" music, and from a Scriptural perspective it was by and large total rubbish. From a purely musical critical perspective it was mostly utterly dreadful tuneless, moronic garbage, hardly worthy of being called music at all. So I don't think Christians have a leg to stand on when they try to dictate to people what they should be listening to.
People such as Mozart were about as carnal and decedent as you can get, yet his music was and is about as spiritually uplifting as music can be.
