I know all about locked and read-only files, but this one has me stumped. I'm reorganizing some of my music folders and updating the metadata because my truck radio shows wrong info while the songs are playing. Everything was going well until I came across a few songs that I knew were released in the 70s, but the "year" field shows something else, like 1997 or 1989. So, I go to change the year and it lets me because the file is not read-only. I hit apply and the year then shows 1977. If I close the properties and reopen, the wrong date is back. I've also tried to erase all of the metadata and it makes a copy with everything erased except for the year, which is wrong. I wasted a whole bunch of time changing a lot of folders and happened to check and they have all reverted back to the wrong year. It is just the year that is affected; everything else retained my changes. I can live with it, but why is it doing that?
