IE _can_ be involved. Whether it really is or not might depend on 
your configuration (installed software and default handlers). You 
could probably try to install WinAmp, allow it to bind all supported 
formats to itself, and check whether the behaviour is the same as 
before (I'd probably try it with mp3). I don't know, whether this 
really overrides IE completely, but hopefully it should.
