I also use a list. It’s got some ridiculous stuff on it – a lot of it pulled from posts at aiweirdness.com – which I won’t necessarily use directly, but something about the sound or shape of the words often inspires a better title.
(I did use the wackier neural network stuff directly when I was cranking material out experimentally and super quickly, so I’ve got some things named “FLlp0oo2dr ST4rr”, “Don’t The Mountain”, “Borb!”, “Snox Boops” etc.
)
I rely on the list for working titles about half the time (the rest of the time, a title suggests itself while I’m working on the thing). And then about 1/4 of the time, I replace the working title before releasing it.
