Spare the Rock..
It's called "Spare the Rock, Spoil the Child." It's a local radio show (in Northampton, Mass.), that uploads all their shows to their website and offers them as podcasts. Anyway, looks like a pretty cool radio show for kids (and parents who dislike the standard children song fare). They play "kid friendly" songs . . . lots of Beatles, They Might Be Giants, obscure bands, and lots of up-tempo, happy songs. (I kind of like listening to it myself - very eclectic)
