while it IS true that Satan uses scripture and masquerades as something good, how do we discern between what is truly good and what isn't?
Should we question every single new thing as being part of Satan's work?
My feeling is this - it goes for secular music, for Rated R movies, for anything that any human being finds to be inappropriate. There is a verse in Romans (don't know which one offhand) that says that if YOU believe it is wrong, then it is wrong, and you shall not participate in those things.
I don't think it says "but if you you think it's good, then it is"!! Just that if you feel that secular music is bad, don't listen to it. If you think Christian rock is evil, then by all means, don't put yourself in earshot of it.
Personally, I can watch a rated R movie (rated R for violence, drugs, whatever) and not want to do those things. I can still separate those things from my life. Granted, most of the movies I watch that include those things view it as BAD, as do I. I don't think I could ever watch a movie that condoned violence.
I will still view those things in a rated R movie as bad, as I will view the plot of the movie as such.... It does not affect me as far as my actions. I try to stay away from graphic movies, but there are some that I have seen.
The same goes for music. I listen to secular music, but it doesn't mean that I am going to go out and have sex with every man I see.
I actually listen to rock music that talks more about love and the reality of life (like about a kid whose dad left him & his family, but he has survived through it all). I'm disgusted by music that is all about sex, violence or anything illegal (drugs, etc)... so does that mean that ALL secular music is bad?
Also, aren't there some hymns that aren't really all that "holy"? Like America the Beautiful is in some hymnals... I don't think that was written to worship God, but we use it, don't we?
Just some food for thought

I don't think all secular music is good, nor do I think it all bad. I don't think Christian Rock is bad, as long as it is TRULY christian Rock, and not just some guy perverting the Word of God in His name.
Sometimes it may take a while to differentiate between those who ARE using God's Word and those who are twisting it into something that it was not meant to be - like Satan does.
sorry to have rambled!!
