I have a set of MP3 files that Windows Media Player just refuses to add to the library. They are placed in the standard My Music folder. I play them in media player. They just won't be listed in the library.
I've tried dragging them and dropping them on the media player but they still don't appear in the library.
I have an identical laptop where I've also copied the mp3 files and they appear in the library fine.
Any ideas what would cause this?
