The problem I have with this mentality is that you think that EVERY song has to have the salvation message. That's not necessary anymore than a preachers EVERY conversation having a salvation message. His attitude should reflect Christ and he should not act,drive,talk etc in such a way as to detract from Christ, but it's unrealistic to think that a preachers EVERY conversation has to have the salvation message any more than a songwriter has to put that in EVERY song.
You are responding to sentiment that was not uttered. I was simply responding to one facet of the post. But too many kids today do believe that thinking Jesus is "cool" is enough. I know. I teach them. They think if they mumble a few words at a camp, they get a free ticket to Heaven. Of course, a whole ton of adults believe the same thing.
I'm not saying every song should be an altar call, but I would expect Christian artists to avoid "shallow christianity". Jesus is not my 'homeboy', He is my Savior.
