Just noticed: AC/DC loses information as a file name because the "/" is replaced with an "_". So if I later did a fill properties from filename, I don't think it would work. A small request, use escaping for "/" (and "\" though I can't think of any groups that have that in their name).

edit: also ':' and '?' (from "Q: Are We Not Men? A: We Are Devo!")
edit: also, changing capitalization, such as beck to Beck, and then "Rename...." to save the change in the file name does not actually change the filename. Could be Windows, since files are case insensitive.
