Preconditions, prerecorded and preplanning all can be shortened by eliminating the pre—.
“We will meet with our opponents when they have met all our conditions.” See how “conditions” in its unadorned state says it all?
“Recorded music has undergone enormous changes in the last few years.” All music is recorded before it is released, so the “pre” adds nothing.
“Our move to our new headquarters will take a lot of planning.” Of course you will plan before you move your headquarters. The “pre” is understood and redundant.
