Music in general isn't sinful. There's acceptable music - the church's own song books and anything deemed "wholesome." Lindsy Stirling or whatever flavorless trend is on tap.
So, a small group of lily white return missionaries performing their "new" and "unique" a capella version of "I'm a Believer" would be put on a pedestal and promoted to death.
The music I enjoy is definitely on their "no play list."
