My thoughts would be to be able (once you have all or most of the the correct info for an album) to be able to write an nfo file into the album folder. it would be also useful if you have some missing info you could add your own into the nfo kodi makes (for instance if you make your own reviews OR you want to expand on your genres or have different moods etc. etc.)
To be able to do this as well would also decrease the load on the scraper servers if you have to re-install. (I know people will say can’t you add the info to musicbrainz or the audiodb) – well yes you can and is something that many do – but if you rely on the scrapers you only get the info that they want you to have – being able to edit YOUR info the way YOU want it may be a plus for the audiophiles out there.
Maybe i’m a bit old school but I like to rely on my own nfo files but am not sure how many others do – at least if you can create a singular nfo for an album you have a physical ,editable file that can be easily amended/expanded upon in a text editor without having to rescrape.
Any thoughts or negative points would be welcome
