As long as we don't confuse "integrity of the music" with narrow mindedness and/or unwillingness to try, or appreciate something new or different, everything should work out just fine.

And, I'm with Larry, in that singing, or performing, over a complete (finished) pre-recorded audio backing, is nothing new. "It's the way pro singers have been cutting albums for years."

Not only albums, but stage and TV shows as well.

Some very famous and well respected artists (including some instrumentalists), have never even met the musicians who played on their recordings.
