Songs for three-year-olds

In preparation for an extended babysitting gig, I'm scanning my computer for good music that might entertain both me and little kids (and not infuriate their parents). It's not that easy. The Chemical Brothers' "Salmon Dance" is perfect except for one teenytiny little f-bomb. The Bosshoss randomly threw two f's into their awesome cover of Outkast's "Hey Ya" (which I just couldn't find an mp3 for). Devendra Banhart's "Little Yellow Spider" is adorable, except for the verse that produces "hooves instead of hands". I could go on.

Still, looking for links to these songs, I found tons of other great stuff (and couldn't find links for some great stuff). Maybe I'll add more when it's properly curated. For now, I'm gonna see what the youngsters think of these songs:
