Why is that?
I would think that as long it's the same file being played over and over,
and that as long as you don't make it too long (say not over 5 minutes)
then it really shouldn't matter, since that one file will be played over
and over and over and over and over and... The VBR differences will be
averaged out, and I would expect that you are going to see at least 5
minutes variance between (seemingly) identical runs anyway.
OTOH, if this means you are *also* volunteering to supply the actual music
files themselves, who am *I* to argue? Besides, that'll save wear and
tear on *my* music files.
