I have been having a very strange issue with iTunes. It started happening before the last update and continues with iTunes12. Firstly, I have gotten a lot of music from greatest hits packages. This means the year tagged on a particular song is often that of the Greatest Hits package rather than when the actual song was released. Earlier this year, I decided to correct that. So I added the correct year to most of my tracks which did not have it. One of my playlists I actually sort by the year so I get a collection of hits moving from 1977 --> 1985. The problem is that iTunes seems to scramble the years on a select set of songs for no particular reason. It seems to so so whenever I open the iTunes store for ANY reason. And it does not scramble to the original date of the greatest hits album. Its something completely random. For example, the first song on my playlist becomes Gloria by Laura Branigan with a new year assigned of 1970. If I play or do a Get Info on this track, it immediately fixes itself and moves back to 1982 both in the setting and position on playlist. I have a whole bunch which assign themselves years 1997 --> 2000 for no good reason. Anyway, I feel I needed to vent and this is my venue of choice. My only conclusion is iTunes SUCKS. I also post in case there is an off chance that there is a setting "Completely Fuck Up Song Year" buried somewhere which I may have checked and somebody knows where it is.
