As far as transferring them to our iPod, have you considered using iTunes Match? For $25/year it allows you cloud access to ANY songs you have downloaded. It has been money well spent for me as I download from many different sites that I find or purchase songs and albums from.
Get a CD with song you want on it, and you plug the cd into your computer and the computer leads you trough the rest. You can't get anything for free, unless you do something like get the cd at the library but I'm pretty sure that's illegal.
