I think humans can't keep track of 5000 of anything.
Marbles, Kittens, or even BIAB styles.
Just too many things.

Perhaps PG Music can switch the approach on styles .
Instead of the ever increasing number of a particular style (lets say samba), try the following
Offer a single samba style then afford users some control how each musician in the "band" plays that particular stye.
There may be some need for a couple more but perhaps less than the 187 that currently exist in biab. (Disclaimer - i have no idea how many samba styles there but there are many)


There are examples of this approach to software based session players. I've used a couple of them. They are quite powerful.
