using MM5 build 2234, I ripped a CD and while tagging the tracks, I observed a strange behavior: although saved into the track, the tags are overwritten with the historical data, when the track is played or a title tag is overwritten.
- The internal rip process has been used.
- Mass rename was used (it had to be applied twice and only on the second renaming I could type non-ASCII UTF-8 characters such as á and ö)
- The tags were saved and checked in an external player (VLC media player) and in Windows native File properties.
- Find more from same... > Folder (My Library) sometimes updates new tags also.
It seems that editing the tags one by one helps to fix the tags and they are not removed later. So, I also have two track were the tags are "fixed". The other 8 tracks have "fluid" tags.
