A fun technique I've used a few times is to make cuts of whatever audio I'm working with, render them as new files, load into itunes (or whatever you use) then create a playlist of the new set to shuffle/repeat mode. Easy to re-route that into a DAW or into a tape player, all the better if you do so while flexing that pause button muscle.
Might not create fast, easy, fluid results at the click of a button but it's certainly a reasonable way to take the process out of your hands a bit and give you new building blocks to work with.
