In Windows Explorer->Tools->Folder Options->File Types, I have set Windows Media Player (WMP) as the default application to open MP3 files, and for any MP3 file on my hard drive, this works. But, when I am in Internet Explorer and try to open an MP3 file via a link to a web page, it always uses QuickTime (which I don't like). Where-o-where is this association being made? Why doesn't IE use my default file association for MP3 files?
