You suggest in order to avoid offence or confusion we should "consider finding something else that is worshipful". This is the issue, what is that something else?
Satan has managed to pervert every form of music, as soon as you think you have the answer Satan copies it, abuses it and then the negative conotations are now associated with it.
As a worship leader any music you select WILL cause offence to someone somewhere depending on their experience.
What do you do?
Christo: You pray and ask GOD what HE would have you minister to the congregation...and allow the Holy Spirit to tell you what is pleasing to Him. Happy Sabbath! =)
