Previously I'd just edited the basic info by right clicking the mp3 in the windows folder, selecting properties and then editing the details in there, they definitely all had the year, title and artist data correctly inputted. Now I'm actually having MM remove data from files, so now I've got over 100 that have no date, no artist, etc.
Two things seems to be occurring with MM, firstly it's obviously remembering some of the data from the files themselves from somewhere, as even if I clear both ID3v1 & v2 in the advanced tag options on MM, when I then go back to edit the file and put some of the correct data back it suddenly fills everything in again, even the zzzz fake album name I gave it ealier. So can I check to see where MM is getting this other info from or stop it making changes unless I tell it to?
Secondly, sometimes it seems to not be seeing the data that I have on the file already and creating blanks where there were none, same thing, can I stop it doing this? I have now unchecked the infer properties option and yet when I delete things in the album section, it still puts them back when I open it back up again, where is it storing and seeing this data from and why does it keep insisting I have data I repeatedly tell it to delete?
I suppose I don't want MM to try and be clever and do anything I've not told it to.
