I am working on a music site which has custom post types- artists, and releases. I have about 3,000 artists, and about 19,000 releases in my database. I'd like to create a new taxonomy term for each of these post types.

I have created a taxonomy called artists. I'd like to have each post of post_type -> 'artist' become a term in the taxonomy, automatically.

I'd then like to do the same with releases.

Anyone have any ideas?

Thanks!
