I'd recommend to add the genre to the recommendet lame settings, as the developers have introduced "--ignore-tag-errors", which is a great option. It should be default behaviour anyway, as otherwise lame.exe terminates with the genre error, which was really annoying.

So with EAC and lame 3.96 (at quality -V 2) maximum tagging fun is:

-V 2 --ignore-tag-errors --tc "your comment" --tt "%t" --ta "%a" --tl "%g" --tn "%n" --ty "%y" --tg "%m" %s %d

Not sure, which version of lame introduced "--ignore-tag-errors"
