I tend to do this as a shell command, and that'd depend on your shell.

For csh variants:

foreach file (*)
mv $file $file.mp3
end

For sh variants (bash, ksh, ...):

for file in * ; do mv $file $file.mp3 ; done


You'll want to read your shell manpages if you want to do stuff like removing
old extensions, etc.
