Oh, man! (slaps forehead) MP3's!

Considering that this had four movements, and only one of them is smaller than 75 mB in WAV files, MP3 is the obvious answer! (I have GOT to get out of the Baroque Period...)

Is there a limit to the size of a .WAV file being posted in this forum? I've been trying to upload a particularly large one and it never quite finishes loading. Am I trying to load too much, or is there something I'm missing here?
