I wish there would be some "magical MP3 split" that acts upon
a specified silence (for example, 3 seconds) and splits the
file into "tracks" that could then be renamed...

There are two articles which I occassionally refer to,
indead of saying "don't use spaces". :-)

David A. Wheeler:
Filenames and Pathnames in Shell: How to do it correctly
http://www.dwheeler.com/essays/filenames-in-shell.html

David A. Wheeler:
Fixing Unix/Linux/POSIX Filenames:
Control Characters (such as Newline), Leading Dashes, and Other Problems
http://www.dwheeler.com/essays/fixing-unix-linux-filenames.html

Those articles will provide you with the most robust
solution - and: no, just adding "quotes" isn't sufficient
in most cases. :-)

Also note: If you're starting to extract information from
an ID3 tag and want to turn that into a directory and filename
structure, you might find other characters than just spaces
that "misbehave" in shell context.
