Now why is it that when you want to be able to fade out one stream and fade in another, that SDL_mixer says "thanks for the new file" and cuts short the old to start up the new. I would have thought it possible to have ogg streams running on different channels, but as yet have been unable to actually stream more than one file. Instead I have to load both files as Chunks (which can cause a slight delay during loading, especially of larger files) and fade the channel that it is operating on (not particularly difficult).

There must be some implementation of SDL_mixer which allows crossfading of streams... surely...
