Thanks for detailed and logical advice, but it didn't work.

First, there was no npqt*.dll file under Seamonkey\plugins, so I tried 
the "about:plugins" trick, which reported that I had QuickTime Plug-in 
7.6.2 installed with the filename npqtplugin.dll.

A search of the C: drive for that file discovered two copies, in
        C:\Program Files\Internet Explorer\PLUGINS
and  C:\Program Files\Quicktime\Plugins

I deleted both--and nothing changed!  (I also searched for npqt*.* to 
make sure there wasn't a variant lurking somewhere else.)  Both Internet 
Explorer and SeaMonkey still insist on playing MP3 files with QuickTime.  
As I mentioned in my first note, Windows Media Player is the program 
associated with MP3 in Windows, so what in the heck is QT doing to force 
the browsers to use it?
