To all you people who love 
Winamp, you must seriously try 
foobar2000.
Although there are some who swear by 
Exact Audio Copy, I personally like the power, features, and configurability of 
CDex.   Also, 
CDex is released under the GPL.
As someone else mentioned, 
FileZilla is a nice <acronym title="File Transfer Protocol">FTP</acronym> client especially for the fact that it is free and 
GPL.
Much thanks to everyone who made suggestions, I learned of a few programs I had never heard of and was reminded of a few I forgot.
