For whatever reason my mac's OS is really screwed up and programs close unexpectedly and it is annoying. I am going to have to reinstall OS X. But my main concern is itunes. I have a lot of songs on my external hard drive that I have on itunes. When I transferred them over some of the track info was messed up but I fixed it all. Afterwards I updated the ID3 tags but does that actually work for song name, artist, album, and album art? I would hate to have to fix all the songs over again when I transfer them back on after I restore my computer.
