I really don't know karaoke bars at all

"Both Sides Now" by Joni Mitchell should not be remixed and have the key changed on an unsuspecting karaoke singer who was thinking she'd be singing a mellow tune, not a dance hit.

Not that there's anything wrong with dance hits. (I have like 5 remixed version of Kelly Clarkson's "Since U Been Gone." Which is, as a side note, always a dedication song for me....)

Almost anything else can be technified. But not Joni Mitchell!
