simple means of editing text of comments/descriptions for FLAC?

I’ve been trying unsuccessfully (for years) to add text to FLAC files, so it shows up when I play a file.

So far I’ve discovered I can paste text into the ‘comments’ section of a FLAC file (using e.g. mp3tag software), and it shows up if I hit ‘i’ while on that track. but is it also possible to edit the general ‘album information’ field?

as a bonus: is there any known way to scrape album reviews (e.g. from Wikipedia ‘critical reception’ or elsewhere).

thanks a lot.
