semi colons, genres, tags....PROBLEMS

Hello,

I'm trying to update my music files' id3 tags and sorting/info in media player.

In media player, I changed an artist's genre from "Jazz - Blues" to "Jazz; Blues".

When I opened the files's properties in Explorer, under details/genre it still read "Jazz - Blues."

I tried again, this time changing another set of song's details/genre from "Jazz - Early" to "Jazz; Ragtime." In WMP, that set of songs still appears under the genre colun as "Jazz - Early."

Help!? Why won't WMP detect the change in id3 tag info if I edit it in the files' properties directly? Why won't WMP change the id3 tag info if I edit it in WMP? How can I get my files to have multiple genre tags instead of using hyphens?

Really? So it will save star ratings in id3 tags...and it will rename, move, and create/delete folders for files...but it won't change id3 tags?

And, moreover, WMP won't detect changes to id3 tags?

wtf....?

Weird. Since genre is a pretty universal property you'd think WMP would read/write it. Funky. Idk, maybe editing there's just a weird delay. I'll check later I suppose.....otherwise, 3rd party apps baby!
