Actually the total size of the track would do better. When you know the 
total playing length too, this can be used for calculating per-track 
bitrate. For total file bitrate you can naturally use the total playback 
time and total file size.. The field for total size has been added to 
the MCF specification now, thanks for supporting us ;)

Added to MCF.

It's already there.
