+1/ -1

I can imagine how useful this might be, however... I am not a fan of software that is tethered to online service, especially 3rd party service.
So, +1 would be if: PGM servers would act as intermediary between BIAB <->AI api. In similar way you audition styles through picker "online". Obviously, unchecked box to use "online" content will untether program from calling home or other "places".

-1 If the process is baked in.... As the one PGM made for "AI lyrics". If it was up to me, I would made that whole "block" as optional enable/disable in preferences. It doesn't belong in Library anyway smile

In short, good idea, but depends how it may be done.
