Well, I guess "%genre%\%comment% %artist% - %album%" should do the trick for the first one. About the second one, not sure since there isn't something which separates the comment from the artist.
I think this is not possible, because - as Sebastian already stated above - there is no special character or string which seperates the comment from the artist. Bad filenames.
Btw: there is no need to write an email, post to the forum and write a PM. Please choose only one option next time.
