To be honest, after being jerked around by WMP for months I was advised to download Jaangle & MP3tag - which is one of the wisest moves I've made.
I couldn't get past the WMP continually rearranging my music, and scattering files and folders all over the place no matter what I did - and I really couldn't make any logical sense why it was doing it.
It seems to me that Microsoft are designing programs to be clever, and okay if you have a physics degree from NASA, but the rest of us find them more and more baffling and unusable and the sooner they wake up to this the better.
I'm not interested in the moronic hidden menus, hidden separators and everything else we have to play hide and seek to find (think crappy windows live mail that is not designed to work for the benefit of the user, but for some clever techie to keep himself in a job)
Sorry I'm unable to help friend
