Limewire Help....?

I currently have Limewire and i really want to uninstall it. But i don't want to loose my music. How could i save them so that they wont get deleted when i uninstall limewire? Also, is there a free site that i could download free mp3 files from instead of limewire? Is there a program better and safer that i could use? i heard ares was good but im not sure. Any help is appreciated, thanks.
