I think Christian musicians are so concerned with appearing ‘goodie’, even if it’s not about worship, so that it’s hard to tap into any real emotion. That’s probably why secular music sounds more ‘authentic’, particularly singer-songwriter type stuff.
For example it’s hard to write about heartbreak when you’re not supposed to appear attached to anything, or anyone. It’s hard to express anger when you’re not supposed to be angry. Hard to express longing when you’re not supposed to long after anything etc.
More than that it’s hard to write something musically interesting when the focus is primarily on the right message, and the music is just the background, something to serve it up with.
Heartbreak, or getting high on cocaine, or what goes on under the board walk with your baby is indeed sung about best by those who experience it and or hope to.
Hymns are written by those who hope to avoid those things or have, and instead are interested in glorifying God, or telling about their experience of having their lives imrpoved by an encounter with God.
So you have expressions of different experiences or aspirations.
Rock and roll is best suited to one and the Christian musicians who adopt its musical style to their lyrics, as others have said here, don’t really do a good job of making rock music. One person wrote correctly that the message does not fit the spirit of Rock and roll. It is indeed a different spirit and the two can not meld together.
People can try to live in both worlds for a time, being drawn to both, but ultimately end up in one or the other. The poster who insists that rock and its culture and message are not spiritually dangerous to souls identifies himself as a heretic.
The message has changed over the decades. At first it was pretty innocent, a little naughty, a little rebellious, then a lot rebellious, then blatant about sex and drugs and party hard, and now it is hos and rape and murder, death and suicide.
Mick Jagger was lowered on stage from the ceiling dressed as the devil. Some nitwit Irish woman singer went on stage and tore up a picture of the pope, her enemy. Michael Jackson is so bizarre that no one can even relate. Janis od’d, Jim Morrisson, Jimi, Curt. The Stones have been heroin addicts for decades. The Dead are all about drugs and Garcia was addicted for decades. Guns and Roses were fueled by coke.
Yep it is all harmless fun. Listening to it can’t hurt anyone.
