you can import tags (any kind, not just genre) via the LastFM task in analysis.
Alternatively, you can of course update the genre tag via the Import Metadata task, but it will overwrite your existing tags—something you might not be interested in.
That all said, are you aware that the Get Info dialog offers alternatives? Just go to its genre field, and right-click on it to see alternatives from different databases (attached screenshot). If the right-click is not offered (no red squiggle), change the existing genre name slightly, i.e. remove a letter.
This is really close to what I'd like to do. Specifically, I want to use AllMusic (not Last.fm) info for all the tracks in my iTunes library, with Genre>Genre and Stye>Grouping. Is this possible? Also, from where does beaTunes pull its Genre information? Apologies if this is an ignorant question, but I'm just starting to use beaTunes and did not see these answers after initial search in KB and discussions.
