The "old-fashioned way" of doing this, (speaking as an old UNIX support 
person), is the following:

uuencode Track.mp3 Track.mp3 > Track.uu
LINES=`wc -l Track.uu`
SPLITLINES=`expr $LINES / 2`
split --lines=$SPLITLINES Track.uu Track

This will produce two uuencoded parts which can then be compressed:

bzip2 Track??

resulting in Trackaa.bz2 and Trackab.bz2

These can be uploaded, and then later downloaded. The reassembly goes like 
this:

bunzip2 Track??.bz2
cat Track?? > Track.uu
uudecode Track.uu

You will now have the EXACT original file, no loss of any kind.
