tempo mapping

I produce lots of copies of songs mainly for theatrical or stage type shows. Over the years I have a pretty standard workflow, but while doing one today, I wondered if others do it my way or have their own system that might be better?

I always use the original song as a template. I tend to do the trickier bits in short chunks. So playing along with the real thing is pretty critical.

It may be a rather childish question but can anyone help out on this. I know some have heard this, but you know that sound, used mostly at the end of pop-punk songs where it sounds as if the song just slows and stops. The most recent example I can think of is in the new Lil Jon song "What you gon do" radio edit version during the chorus on the word $hit.
