5. The Singable Songs Collection
This is actually a three-CD Raffi set that includes the Canadian troubadour's first three albums. But it comes in one package, and these albums, especially the first two are stone-cold kids music essentials. Parents who only know Raffi by reputation and dismiss him out-of-hand are missing his sometimes frisky renditions of kids classics (re-popularized thanks to him) and, especially, his voice, which might just be the best in kids music.
