I'd love to be able to update the YEAR field in iTunes by using on-line music databases like ALLMUSICGUIDE.com or Amazon, there is a great program called iART that uses Amazon to update the Album names and the embedded art files, but not the year the album was first released. I think it'd be great to be able to set up a Smart Playlist of all 70's rock tunes, or 80's rock without having to put use the genre field which most people seem to do.
