I know many people have had problems converting .wma music files to music files that will play in their iTunes. There are several ways you can do this. If you are using a non-Mac, simply download the PC version of iTunes, and drag and drop the music files into the library, and iTunes will do the conversion for you. If you are on a Mac, I have only found one action so far that actually works. It is called ffmpegX. It basically is a simply drag-drop converter that will allow you to play your .wma files in iTunes. The only problem I have found so far is that I don’t think you can convert bulk… you have to do it one at a time. However, it goes very quick, and doesn’t take long to convert 100 songs. It is worth a shot as a last resort if you have no other options, that are free at least.
