Best place to adjust match results

hi there.
I’ve just started playing with beets and I’m looking for a way to alter results coming from discogs / mb; before they get compared with files and eventually applied. since most of my existing tags are lower-case (just like it that way), I’d like to lower the incoming results.
what’s the best place to do it? or the best way to write a plugin for it?
i’m playing with templates, but it looks like they are good for paths right now.
thanks!

Yep! We don’t have an exposed way to modify results “on the fly” like this in a configuration file or similar, so a plugin would be the right thing. Given an appropriate place to hook in, what you’ll want to modify is the candidates field on ImportTask objects.

Thanks. Will give it a try.
